I'm a little paranoid....I got a worm recently. Panda antivirus found it and removed it. Coincidently somebody obtained access to one of my web page accounts and left an obvious message that they breached my security. The password for my account was really long and convuluted so I'm wondering if I have a trojan or something to that effect on my system. Panda hasn't found anything, but I'm curious if it would find something, if the anti-virus software was installed after the incident.

I have zone alarm pro now, but it only asks me if I want "x-file" to access the internet...saying that it has accessed the internet before....unfortunately if zone alarm pro was installed after the trojan was...then it would only be telling me that "trojan x" has already accessed the internet...so do not worry about it.

Basically...what should I do...besides wiping out my system and reinstalling everything.

Is there some utility that is designed to catch trojan-like viruses?
