A competent antivirus program needs to be able to keep your system safe from a number of different kinds of programs of ill intent – things that they call malware. This isn't as straightforward a thing as you might imagine. Good antivirus software needs to be able to rid your system of any viruses that may already be there when you buy antivirus software and install it. It needs to be able to detect any new viruses that turn up after you install your software, and it needs to be able to do all of this without using up too much of your computer's power.
Look up reviews before you buy antivirus software, and you'll usually find that the major names are often capable in one or another of these areas; only rarely do you find a product that's good in more than one area.
Nearly any company that you look at, they usually sell antivirus in a couple of different versions. Basic antivirus software takes care of all possible infectious agents. They also offer you antivirus as part of a security suite – a clutch of different programs that work together to completely protect your computer. These usually include spyware protection, spam protection, a firewall, parental controls and so on.
