An anti-virus program is one of the very first things you should install on a new computer. You may think you’re covered because your computer had [Big Name Anti-Virus] pre-loaded when you bought it. But look carefully: you’ll probably find that what you have is a 30- or 60-day trial version. At the end of that trial period the program will stop updating itself unless you pay a subscription fee.
If you don’t subscribe, you’ll still be protected against the catalog of threats that were current in the last update, but you won’t be protected against anything new — and new threats come along all the time!
Avast! is an excellent, free alternative to those big-name commercial anti-virus programs. If you’re paying for one of those, you should switch. If you’re NOT paying for one of those (and you haven’t chosen anything else), you especially need this!
Avast! will protect your computer from viruses and spyware while you browse the web and use email.
There are other free anti-virus alternatives, too, but this is the one I’ve used on all my computers for almost 10 years, so this is the one I recommend.
