I agree with previous posts-switch to Opera as it checks every site before it loads it up. If the site is blacklisted it will give you a warning. If you want to be on an even safer side, browse the web with Linux. A techie friend of mine said it could even run from a CD rom. This will of course not save you if the virus is in the zip. AVG is pretty good but I found it dormant sometime because I happened to have a trojan downloader which it only detected once in the system restore file. One could of course argue that it was a false positive but I got rid of the restore file to make sure... Anyway, Opera is a good choice, but sadly isn't supported everywhere. I have issues with some forums for instance. Good luck!
