I have a poorly Win 7 PC, brimming full of nasty Trojans that I want to get rid of. Only realised something was amiss last night as the internet connection started playing silly buggers (modem working, router working, connecting to home network but not to the web...).

Currently running a scan with Avira to try to catch/identify as much stuff as I can. At 11% through the scan it's already detected 32 problem files, including several trojans. This machine has been off the web completely until a month ago, when I finally gave in to register software and automatically download updates!

Anyway, the thing is, the web's a useful place but I don't know which sites are good and which to trust — so, trusting those round here a bit more...

1) Can anyone recommend a good place for checking what each trojan/virus etc does and the best methods for removal?

2) Is there anything other than Avira I should be running? Though I can download programmes on the Mac and transfer them over to the PC for installation, it obviously can't be anything that requires web access to run (like McAfee did... duh!), obviously.

I'm on Win 7 Ultimate 64-bit.

Thanks in advance...
