Earlier in the week AVG popped up to tell me it'd found a trojan. I moved it to the virus vault and deleted it. A few minutes later, I opened IE7 and had a page looking like a Windows warning screen but clearly not, giving me spyware warnings, click here to fix them, click here to continue surfing, etc. Then the Windows Firewall popped open to tell me it had blocked something, that may have had a keylogging function, and did I want it to keep on blocking it. Yes, I clicked. I immediately disconnected from the internet, ran full scans with AVG, Spybot, and Windows Defender, all of which brought up nothing. I even searched the registry for terms such as "keylog" and "trojan", and found nothing. Reconnected to the internet and everything was normal, and has been ever since other than me being a little paranoid and using the on-screen keyboard for entering any details which are even vaguely potentially sensitive, rather than typing, which is a bit of a pain. All I want to know is whether, with all the scans and everything, I'm in the clear, or whether there's anything else I should do before assuming I am. I'm using Vista Home Premium, if that's of interest/use. Thanks for reading and for any help or advice.
