It’s no secret that PCs are vulnerable to virus attacks. Nobody wants their computers to be attacked, their data destroyed, or worse, their personal details stolen, which is why it’s so important to protect your PC against unwanted intruders. Here we have a look at some of the commonest kinds of PC viruses, and how you can protect yourself from them:

Helper Viruses

Sometimes called anti-virus viruses, these bugs work to infiltrate your anti-virus software. They get nothing from this themselves, they are simply helping open the gates to other, different viruses. Think of them as the guy that picks the locks, so that the other guy can get into your house. The only way to protect yourself from these kinds of viruses is by not only having one kind of anti-virus software, many people run anti-malware or anti-spyware software as well as their normal anti-virus programme.

Secret Viruses

This kind of bug infects your system and then replaces your own files with files of its own, it then convinces your computer that the files are the original ones and haven’t been changed. This form of virus is a particularly common one, but fortunately you can combat them with a good anti-virus programme. Most advanced programmes nowadays will recognise secret viruses, but make sure you have you anti-virus software set up correctly and that you actually use it!

Time Delayed Viruses

You might think that you can protect yourself by simply running your anti-virus software every time you go off line, and you’ll be fine. Time delayed viruses are the reason that this doesn’t work. These viruses infect your computer, but then lie hidden and inactive for days, sometimes months, at a time, before they start doing their work. To protect yourself, make sure you run your anti-virus programme every three or four days, minimum once a week, to catch all those bugs that may have been lurking in your system for a while.

Bad Penny Viruses

This in one of the oldest forms of computer virus, and works like a bad penny. It compromises your computer system, and then goes on to affect everyone in your network, or everyone in your email directory. The whole reason that firewalls were invented is because of Bad Penny viruses, which should tell you something about how to protect yourself. Make sure that your firewalls are turned on, and set to the highest security settings. Running anti-virus software is no good unless you’re running firewalls too. Don’t forget about them.

Encrypted Viruses

These viruses are the scariest form of bug out there. They are regular computer viruses that infect your files, however they are encrypted. Because all the virus starter has to do is change the encryption key to change the virus, they are particularly difficult for anti-virus programmes to detect, new encryptions come out all the time. The best way to protect yourself from these is to make sure that you regularly download the updates for your anti-virus software. These updates will contain information for your software about new encryptions that have been found, so they are important to help you software notice bugs in your computer.
