Don’t click on links in those CNN or MSNBC “news alerts”! Or similar ones that will appear in your mailbox.
Bad viruses and spyware will happen, along with possible identity and financial theft. Don’t even try the “unsubscribe” links.
If you think you have problems with spyware, then a great resource is the “Hijack This” folks. Start with their tutorial here to get the HijackThis! software, and to submit your results. Make sure you carefully follow the tutorial. Those guys really know how to get rid of malware. I use them after the anti-virus and anti-spyware software can’t do anything.
You might also try the Microsoft on-line scanner (www.microsoft.com/protect ) and their Windows Defender program (both free).
And don’t forget your updates of all software (not just Microsoft).
