I'm talking about home machines or small office machines. Big company setups, like Sony, are a whole different kettle of fish. But for us home users, there are some simple things that will improve your odds.
1. Turn the machine off when not in use. It cannot catch a virus off the internet if it is powered down.
2. Never, ever, click on an email attachment. No matter who the email is from. Your best friend may have been infected by a virus, and virii, will use the address book in the infected machine to email themselves far and wide. Attachments can contain malicious code that executes as soon as you click. If you just have to see what is in the attachment, save it to disk, and inspect it with a low speed text editor, like notepad, or wordpad. Word itself contains a powerful BASIC interpreter that can do all kinds of damage when presented with malicious code in an attachment.
3. Run a virus scanner now and then. There are a lot of 'em. Avast is good, and so is malwarebytes.
4. Run Windows Task Manager now and then. Check the "process" window. Processes are programs running on your machine. There should not be more than 30 processes running. Check out strange processes, or processes that seem to be taking up too much CPU time or ram. Click on the CPU or Memory Usage columns and Task manager will rearrange the display with greatest CPU or Memory Usage at the top. Google on the names of ramhogs or CPU hogs to find out what they are. When you get a solid ID, such as "well known virus" go after it. Find it on disk and zap it. Find any references in the registry with Regedit, and zap them.
5. Music download sites are virus infected.
Good luck.

Oh yeah, I forgot to mention, dump Internet Explorer. It is terribly vulnerable and has a bunch of gaping security holes. I use Firefox and find it very satisfactory. Chrome is becoming more and more popular. I haven't tried it myself, but more and more visitors to this blog are using it. Stop using Internet Exploder and your computer will thank you.
