Ok, just out of curiosity I installed Avast on my Windows PC, updated it... ran full scan (for over an hour) and of course "nothing found"

A firewall will not save you if you download a trojan and run it. A firewall simply blocks unused network ports so that no information can come in or be sent out. So if you ALREADY have a virus on your machine, it won't be able to spread out to other PC's. The virus will still be there and running, it just won't be able to multiply.

1. If you HAVE TO run Windows, make sure you install all security and critical updates:
http://windowsupdate.microsoft.com/ (if you have anything older than Win 2000, you're screwed)
2. Go to "Control Panel" -> "Users" and make a "Restricted" account and an "Administrator" account. Set passwords for both. Use the "Restricted" account for browsing the net. The "Restricted" account will not be able to install new programs (including spyware or adware) or edit your system files.
3. Go to "Control Panel" -> "Administrative Tools" -> "Services" and disable dangerous services like "Messenger", "Telnet" and stupid ones line "Indexing Service"... this guy explains what each service does read his tutorial:

4. Use a browser other than IExplorer, for example Mozilla(
http://www.mozilla.com/firefox/ ) If you MUST use explorer, go to "Internet Explorer" -> "Tools" -> "Options" and disable "3rd Party Browser Extensions"
5. When browsing the net, never, ever, EVER accept scripts when asked by ANY website. Example:

Be especially cautious with anything called "integrated," "search," "toolbar," "optimizer," "automatic" and so on
6. Don't belive in anything you read in an e-mail (especially if it asks you to "log-in here" or "update your information") NEVER, EVER, EVER click on links found in a e-mail. NEVER download attachments from an e-mail (unless it's from a friend) Don't give out your personal e-mail to any web site you're not familiar with.
7. Run a firewall if you're still paranoid
8. General security: Try not to store passwords (turn off "Auto complete") or personal information on your PC or remotely on any web site. Use different passwords for your mail, messenger, etc... Make each pass more than 6 chars, letters and numbers, no dictionary words... you know the routine
