The only effective way to remove computer viruses and worms is to get a good antivirus program.
There are many of them on the market.
If you educate yourself about viruses and worms first, you will be in a better position to choose the right antivirus for you.
In a nutshell, a computer virus is a small snippet of computer code that enters a computer from an outside source.
It is called a virus because, just like a virus that enters your body, it does your computer damage.
It can either be a nuisance virus like the common cold or it can be deadly to your computer's operating system.
It is a mistake to think that just because you have installed an antivirus program on your computer, you are protected from viruses.
The hackers who make the viruses continually change them in order to slip through the antivirus programs.
Therefore, you must update your program every day to ensure it can locate all the latest viruses.
Worms differ from viruses in that they reproduce themselves.
A worm can install itself in one drive of your computer and then duplicate itself and install itself on another.
It can also travel from one computer to another.
You may have accidentally sent a worm to someone else in an email and not known you did it and vice versa.
In addition to installing a good antivirus program and keeping it current, they are other precautions you should take, as well.
Always use firewalled applications.
The firewall blocks viruses and worms from entering your computer.
Another thing you should do is update your operating system regularly.
Be careful with email attachments.
Only open those that come from trusted sources and use an email client or antivirus that scans attachments before it allows them to be opened.
It's a good idea to set your antivirus on automatic update.
That way you won't forget to do it yourself.
If you take these precautions, you should be protected from viruses and worms and have a trouble-free computer.
