I had a recent attack by something called Vundo, among other names. Very frustrating. I hired an online expert to get rid of it and she did. Now (three weeks or so later) it has attacked again. My McAfee Security Center spotted it and took it down, so I guess I'm okay. The question is, is there a way to find out where it comes from? I do not open unsolicited email attachments, do not go to porn or gambling sites, use a strong password, keep my firewall up at all times, and so forth, so I am not doing something stupid. I do go to a lot of sites. Is there a way to tell which one has this trojan lurking?
