not had anything for a week or two since changing.
I was using Microsoft Security Essensials, but it let some stuff in, so Im now using Comodo Firewall, Spybot, and NOD32 as my virus scanner. Using Firefox as my web browser, was using opera, but went back to firefox as I believe opera was also something to do with things getting in.
Seems to be a lot more secure now, not had anything for a week or two since changing.
How did you get them?
Do you have a router?
I've not seen a virus prompt for about 7 years on any of my own machines, not including one or two false positives
Im using a Linksys WRT54GS, dont think that has any firewall stuff but i may be wrong?
