This is my first post to this site. I think I have been infected with the Personal Antivirus trojan. I'm sure I contracted it while on Facebook. While on FB, I received a popup telling me I had undetected threats on my computer. Not believing the popup I clicked on it to close it, but apparently the entire window was programmed to start scanning. I was able to cancel the scan and close the window.
After a while I noticed that the FaceBook site was running very slowly and jerky. I logged off and performed a scan with Norton Internet security, which was fully up to date. It only found some cookies, which I removed. A few day later, I encountered the popup again. This time I just shut down the computer. I rebooted and performed an online scan from Panda software, which found nothing. I also performed another full scan with NIS which only revealed cookies.
Then, yesterday, while on Facebook, I was playing a game which was acting very strangely. So, I shutdown again, rebooted and My Verizon Help and Support window came up to perform an update, which lasted quite some time. I was suspicious so I canceled the update. I downloaded Sophos threat detection software, which found the trojan. Then I performed an online scan with McAfee, which also found the trojan. Of course, they could not remove it. I then performed another scan with my installed NIS, which found nothing. Sorry about the long story, but I wanted to give you a good idea of what I've done so far. I am really at a loss as to what to do. I'm not sure if Sophos or McAfee are just showing a false positive or if my NIS is somehow tampered with.
I found quietman7's 5/19/09 reply to Egoxto who who seemed to have the same problem and the steps he took to remove the trojan.
However, I don't want to do anything without someone leading me, since it seems there is some registry editing, which I have never done.
I'll wait for a reply, before i do anything. Thank you so much for your help!
