Been using Nod32 now for almost 12 months, its been fantastic Lately I've been having problem with my Windows XP Firewall.. It will auto disable itself, over and over each time I turn it back on. A complete scan with Nod32 did not detect anything, so I tried another antivirus program. 'eTrust' is what I tried, and it detected a 'Backdoor-CCB' Trojan located in my scvhost.exe file which was causing the problem. I would have sent in a copy of it, but its been removed from my system now. I'm pretty sure I know where I got it from to start with, so I may even download the file again just so I can send in the trojan for the Nod32 guys to see.
