Safeguard Your Computer With Antivirus Software

Filed under: Uncategorized — Tags: advice, antivirus, computers, entertainment, family, hacking, home business, internet, kids and teens, other, recreation, security, software, Study, Uncategorized — Owen Jones @ 6:13 pm

Computers run so much of our lives these days. They run our payroll, our bank account, our school and business records, our governments and, for many individuals, our entertainment, so anything that disrupts computers has the potential to completely screw up our lives in the short term.

This state of affairs is awful enough, but there are also people out there who get their thrills out of composing and releasing viruses to infect our computers and screw up our lives. I am not talking about criminals, we have always had to put up with them, I mean kids and others who write and release viruses to damage our computers for fun.

These days, a lot of families are dispersed because members have travelled to other cities to study or work and sometimes this means going to other countries too. Most of these people rely on computers and the Net to stay in touch. A infection could mean the disruption of these contacts and even the obliteration of family photo albums.

You might come to the conclusion that we rely on computers too much and lots of people would agree with you, especially those who have lost crucial information to computer viruses. At worst, you could have your identity stolen and have our financial life completely disrupted, but even losing your computer for a couple of days whilst it is repaired ‘in the shop’ is bad enough.

In my case, this would mean loss of income, for others it may mean a violation of privacy or even theft. So, what should we do to safeguard ourselves?

Antivirus software is the solution.

Antivirus software used to mean a program to scan files coming into your computer, but these days it means far more. Decent AV software will now include a firewall to protect your computer from being hacked and a malware scanner to stop incoming files from dropping trojans and worms etc onto your hard disk.

These small programs can read the keys that you press and send the information back to their creator. These key presses can be analyzed to disclose your preferences on search engines (in order to spam you) or your log in particulars to your bank (in order to steal from you).

So, you have to install either a good antivirus software suite, which will include all of the above or you could get the components individually. Not so long ago, you would have had to purchase all these things, but now some are built into Windows. Windows now comes with a firewall and antivirus software, which will also scan email.

This is powerful enough for most users, but if you want to take your computer’s safety to another level, you ought to add a dedicated malware scanner, of which there are loads of good free ones. If you consider that it takes too much time to run two or three separate programs and keep them up to date or if you would like a higher level of protection, you may consider purchasing an AV software suite.

There are lots of decent ones like Norton, Nod, Kaspersky and others which cost little more than $30 a year for absolute peace of mind.

The Benefits Of Off-site Data Storage

Filed under: Uncategorized — Tags: antivirus, backups, business, computers, data storage, hacking, hobbies, home business, internet, office, other, security, software, spam, Uncategorized — Owen Jones @ 4:16 pm

Everybody who utilizes a computer for any reason ought to take backups. Even if you just play games on your computer, you will like to keep a note of your highest score and your place in the game, but if you run a business with that computer, then backups are even more vital. They are absolutely crucial.

Data is an important tool in any business and it is necessary for an IT business – it is the earnings stream, the more vital your data is, the more you should cherish your data backups. Most individuals store their data backups on removable disks – thirty years ago it would have been on tape or 4.25 inch floppy disks; twenty years ago, it would have been on 2.5 inch disks and ten years ago until now on CD.

However, none of these media is completely safe. Data on these traditional media is prone to deterioration, a type of natural wastage. However, they can also be destroyed in a fire or by magnetic objects, get stolen or become lost. This is not actually an acceptable situation for a business that relies on its data.

So what is the solution? IT experts have been struggling with that question for fifty years. Off-site storage is one solution. This means that you should make at least two backups of your data at given points during the day, put one in your office safe and send one by courier to a safe storage depot owned either by yourself or by a data storage firm.

This is still the system that most companies use, if they back up their data on a ordinary basis at all. It is inexpensive and at least two times as safe as storing your backup data on the office premises. After all, it is extremely unlikely that two buildings will burn down or get robbed on the same day.

However, that still relies on the data being backed up correctly. For data to get securely backed up, it ought to get backed up and then verified. If you have much data this can become a lengthy process if you merely have one or two aging PC’s in the office. If this is a fact, people often skip verification or just back up in the right manner once a week.

I have been in both these situation. Fifteen years ago, I did not verify our company data and had three months of unusable rubbish, when our hard drive crashed, because I had not verified it and something was wrong with the back up program and ten years ago, I had a good backup, but it was a week old and had to pay my secretary a week’s overtime to re-input that week’s data.

Nowadays, I create all my backups by the book, but by a new course of action. I now use a cloud drive. This sounds fanciful, but what it means is that i send my data to another firm somewhere in the world automatically over the Internet every day. It happens in the background automatically. You merely set the program up, tell it what data to backup and off it goes.

This is the best form of data backup that I have ever discovered and it is cheap to free. A number of firms offer free storage up to a limited amount of bandwidth or data storage capacity. Merely type ‘cloud data storage’ into a search engine. Now all you have to worry about is what happens if the Net goes down.

How To Plan For Data Loss

Filed under: Uncategorized — Tags: antivirus, computers, entertainment, hacking, hobbies, home business, internet, kids and teens, other, recreation, security, software, spam, Study, Uncategorized — Owen Jones @ 2:53 pm

If you earn your money by using a computer, you ought to protect yourself against all computer disasters. If you were a taxi driver, you would take out car and public liability insurance. If you were an employer, you might take out plant and tools insurance. If you were a landlord you would take out property insurance and loss of income insurance.

However, what do you do if you toil on line? Well, when you work with computers, data is your most precious resource, but you cannot insure against losing it because you cannot prove that you ever had it. So, what can you do? The answer is that you need to have reliable backups and several of them.

The problem is that computers do not really break down very often so we become lulled into the false feeling of security that we can make backups tomorrow instead of right now. However, the longer that you work with IT, the more you comprehend that there are no warning signs when you are about to lose all your data, which may be your entire earnings stream.

For instance, say you make websites for a living and update them frequently so that the search engines find them interesting. What would occur if your hard drive crashed or if they were destroyed by a virus? You might say that you would download them from your Net host and begin again, but that is not feasible, because most HTML editors will not decompile a completed website.

That would mean that you could never update those web sites again, so they would become less and less interesting to the search engines, so your ranking would fall and your earnings would plunge. And why? Because you failed to insure your business by taking adequate backups. You failed to make proviso for data recovery in the event of data loss.

However, no matter how often you backup your data on physical media, you will always be running a risk because anything physical, any item is prone to failure and deterioration. CD’s do not last as long as we were promised. I have lost tons of data that I thought was safe on CD’s and hard drives are prone to fail with no notice at all.

Even if you do overcome these issues of storage, what occurs if there is a fire or a thief really steals all your disks and computers? Your hardware would be insured but your livelihood, your data would be gone forever. All that hard effort. Your source of earnings. Gone. Forever.

There is a different alternative and that is not to hold your data on your computer, in your office or anywhere within a thousand miles of yourself. This is called cloud storage or cloud data storage. Microsoft calls it Sky Drive and offers 25 GB of free, password-protected, storage available from anywhere in the world. This kind of storage is the best in safe storage providing the best value recovery planning for computer data.

Free Malware Programs

Most people are conscious of the proliferation of viruses, bugs, trojans, worms, spyware and other malicious malware on the Internet, but millions of people, including experienced surfers get hit each day. How can that happen, you may ask.

It so happens that, sometimes, people forget to set automatic updates of the virus database, sometimes the antivirus software is not set up properly and sometimes it just gets switched off by accident or by software.

It is not extraordinary for automatic antivirus software updates to be switched off by accident or design. It has happened to me two times this year already. Luckily, Windows 7 warned me and I took notice of that admonition and, most importantly, I fixed the problem.

This is the most important point. If your computer warns you about something, particularly regarding security, do not put off doing something about it. In fact, drop what you are doing and fix the problem immediately.

If you leave you computer open to assault by malevolent software, you will suffer. It is no good imagining that you are safe because you do not do online banking or because you do not have sensitive information on your computer, because you have.

Your friends and colleagues entrusted you with their email addresses and names on the understanding that you safeguard their confidentiality.

A lot of malware just looks for the addresses in your email client software. Then it will harvest those details and spam your friends to distraction. Two of my friends let that happen this year and the only answer for both of them was to get a new email address and reformat their hard drive.

For instance, I was getting financial advice from my next door neighbour’s ten-year old kid. It was spam coming from Eastern Europe but it was prepared as if it came from him. He had been hacked and his address book had been copied to spammers. I had hundreds of junk email for months.

And do not think that you can merely create a filter to send it to the bin. You cannot, because they forge the email headers so that it seems to your anti spam software that every email comes from a new address, the result of which is that your spam filter does not recognise it as spam.

This is bad enough, but it can get a lot worse. Spyware can sit on your computer reading the keys that you press and transmitting the data back to the boss so that they can spam you on what you just typed.

Does that sound familiar? Today you send email to a friend saying that you are going to repaint and the next day you receive unsolicited email advertising on paint and wallpaper.

If all this sounds familiar, then you ought to take action. Type ‘free anti virus software’ into a search engine and set it up properly. If you have AV software already, check the settings. You need to enable automatic updates.

If you leave your computer always on that is all you have to do, but if you switch it off while not in use, set the updates to take place when you switch it on.

The Best In The Antivirus Industry

Filed under: Uncategorized — Tags: advice, anti-virus, computers, entertainment, family, hacking, home business, internet, kids and teens, other, recreation, security, software, Study, Uncategorized — Owen Jones @ 9:47 am

Most computer users in the United States have heard of the leading American antivirus vendors. Manufacturers such as Symantec, McAfee, Computer Associates, and Trend Micro. These companies have a market leading presence in the United States. Microsoft, too, has aspirations to become a key player in this enormous growth market.

In fact, Microsoft bought intellectual property and technology rights from GeCad software in 2003, a company situated in Bucharest, Romania. They also acquired Pelican Software, which had a behaviour orientated security product, as well as the Giant Company Software for spyware and Sybari Software, which managed virus, spam, and phishing filtering.

A great deal of debate centered on whether Microsoft would end up in a domineering position in the antivirus market by simply bundling its newly acquired software technologies up with its Windows operating systems at no cost. This is a comparable technique that has been used in other markets such as word processing and Internet browsers. In fact, this is precisely what did take place. Microsoft has come out with a free product called Microsoft Security Essentials.

It is too early for me to tell whether MS Security Essentials is a world-class antivirus product, but it is not free to everyone. Microsoft has been struggling with Windows piracy for a while now with its Windows Genuine Advantage sneaky download and sure enough, this new product from Microsoft will only work on Windows systems and even then, only with operating systems that pass the Windows Genuine Advantage check. (Please click the link at the bottom the page to find out more).

There is nothing wrong with that per se, but it does mean that hardly anyone in the Third World will be able to make use of it, because a pirated operating system comes bundled with every computer that I have ever seen in Asia and probably elsewhere too. People save for years in order to afford a computer and the last thing they worry about when they plug it in is whether the operating system is genuine or not.

Of course there is a number of other antivirus manufacturers prominent in this market. There are many companies with great market presence in other countries that are beginning to become more widely recognized. These vendors include GriSoft from the Czech Republic, Sophos from the United Kingdom, Panda Software from Spain, Kaspersky from Russia, SoftWin from Romania, F-Secure from Finland, Norman from Norway, Arcabit from Poland, VirusBuster from Hungary, Nod from Thailand and AhnLab from South Korea.

It is not yet apparent where the industry is heading and everyone in this market faces a swiftly changing scenario. The amount of effort required to discover and deliver updates for new viruses is quite astonishing. Malicious programs are becoming more and more complicated and the quantity of them is increasing.

Many companies may find themselves without the capital to equal the hard work of those truly determined to create chaos. The antivirus companies are receiving hundreds of new examples of viruses a day! What is more, the new viruses are getting “cleverer” in that they spread themselves quickly and they often hide themselves too. Some are even intelligent enough to move around in a system by renaming themselves in an effort to make it hard to remove them.

Computer Virus Examples

New computer viruses are being created, exposed and fought every day. These computer viruses are created often just to annoy us and to wreak mayhem in our computer systems. Below, I have described ten viruses currently cited as being the most widespread and being potentially able to cause the most damage. However, new viruses are being created daily, so this list is by no means complete. The only thing you can do is stay alert, keep your anti-virus software updated, and stay aware of the current computer virus threats.

Virus: Trojan.Lodear: A Trojan (from Trojan Horse) that attempts to download files from a remote source. It will inject a .dll file into the EXPLORER.EXE process causing system instability.

Virus: W32.Beagle.CO@mm: A mass-mailing worm that lowers security settings. It can delete security-related registry sub keys and may prevent admittance to security-related websites.

Virus: Backdoor.Zagaban: A Trojan that allows the infected computer to be operated as a covert proxy and which may degrade network performance.

Virus: W32/Netsky-P: A mass-mailing worm which spreads by emailing itself to addresses harvested from files on the local drives.

Virus: W32/Mytob-GH: A mass-mailing worm and IRC backdoor Trojan for the Windows platform. Messages sent by this worm will have the subject chosen randomly from a list including titles such as: Notice of account limitation, Email Account Suspension, Security measures, Members Support, Important Notification.

Virus: W32/Mytob-EX: A mass-mailing worm and IRC backdoor Trojan similar in nature to W32-Mytob-GH. W32/Mytob- EX runs continuously in the background, providing a backdoor server which allows a remote hacker to gain access and control over your computer via IRC channels. This virus propagates by sending itself to email attachments harvested from your email address book.

Virus: W32/Mytob-AS, Mytob-BE, Mytob-C, and Mytob-ER: This family of worm variations possesses similar characteristics in terms of what they are able to do. They are mass-mailing worms with backdoor functionality that can be controlled through the Internet Relay Chat (IRC) network. Furthermore, they can propagate themselves through email and through various operating system vulnerabilities such as the LSASS (MS04-011).

Virus: Zafi-D: A mass-mailing worm and a peer-to-peer worm which replicates itself to the Windows system folder with the filename Norton Update.exe. It can then generate a number of files in the Windows system folder with filenames made up of 8 random characters and a DLL extension. W32/Zafi-D replicates itself to folders with names containing words like ‘share’, ‘upload’, or ‘music’ as ‘ICQ 2005a new!.exe’ or ‘winamp 5.7 new!.exe’. W32/Zafi-D will also show a fake error message box with the caption “CRC: 04F6Bh” and the text “Error in packed file!”.

Virus: W32/Netsky-D: A mass-mailing worm with IRC backdoor functionality which can also infect computers vulnerable to the LSASS (MS04-011) exploit.

Virus: W32/Zafi-B: A peer-to-peer (P2P) and email worm that will reproduce itself to the Windows system folder as a randomly named EXE file. This worm will check for the presence of an Internet connection by attempting to connect to google.com or microsoft.com. A bilingual, worm with an attached Hungarian political text message box which translates to ?We demand that the government accommodates the homeless, tightens up the penal code and VOTES FOR THE DEATH PENALTY to cut down the increasing crime. Jun. 2004, P?cs (SNAF Team)?

Spyware, Adware and Antivirus

Adware, spyware and anti-virus software share some similarities, one of which is that all three are major problems for computer users. Let’s make a distinction between the three.

Spyware is software that does not necessarily harm your computer. What it does is build links whereby someone else apart from the computer owner can communicate from that computer. Normally spyware records the different kinds of web sites you go to and sends that information to web advertisers, who then later send you unwanted emails and pop-ups.

Which is why spyware is disliked and avoided. It is more invasive than adware. Spyware has its own separate executable programs, which allow it to record your keystrokes, scan files on your hard disks and look at other applications that you use, including but not limited to chat programs, cookies and Web browser settings.

Spyware then sends the data that it had gathered to the spyware author. The author will then use this data for advertising and marketing purposes. They also sell the information to advertisers and other parties.

Adware, on the other hand, is a more legitimate sort of software.. It is similar to spyware but adware is advertising spyware which is packaged into free software or a free program and is installed automatically once that particular program or software is loaded into your computer system.

Some types of adware, on the other hand, download advertising content when a particular application is being run. Some adware acts like spyware in that it tracks and reports user information to the program’s authors.

The signs of spyware infection include pop-up ads that seem to be unrelated to the site you are looking at. Sometimes spyware pop-ups are advertisements about adult contents. Furthermore, if you become aware of your computer slowing down, there is a big chance that spyware and its components have found their way into your operating system. If Windows desktop takes a long time to load, it is best to scan your computer for spyware infections.

Viruses, on the other hand, are a destructive type of software. They were designed and created for one purpose alone and that is to inflict havoc on your computer. They may destroy whatever data they come in contact with, can instigate self replication and then infect as many components of the computer’s operating system or network as possible.

These days, a lot of anti-virus software also offers spyware and adware scanning and removal utilities. They then remove it as well as its components located in the system registry and other places on your computer. It is therefore, good practice to regularly update your anti-virus and anti-spyware scanner to ensure that your computer is protected from the thousands of spyware and viruses in the Internet. Beware of free add-ons or free anything really.

Adware could be spyware in disguise and could be just waiting to be deployed for its writers to gather your data. Learn how to set up a firewall and pop-up blocker in order to minimize the risk of computer infection and guarantee the security of all your computer files.
