Question on what Trace.Known means, exactly

[Veritor]

I have a fully updated Windows 7 system I use---and scan---all the time. Was using FREE and had just done a scan which came up with nothing. Decided to upgrade to PRO since I do like your product. Did so and then ran a scan and obtained these "Trace.Known Threat Sources."

I have friends have seen this and they just clean them up and move on. I can't find much info on these on your site or the web. Is this a specific known risk? The irony is in this case the previous FREE scan was 2 days earlier and I hadn't visited any questional sources in that time. The earlier scans in the LOG have never shown this kind of detection going back for weeks. I never go to a link that hasn't been cleared by Norton.

SaS says it cleaned these fine but should I be more concerned?

That detection means you visited a website determined to be "bad" and those items in the IE cache are from that website. This could be simply going to a website that offers a program considered to be adware. You don't need to do anything except remove those items.

[Veritor]

So, not to sound too much like a noob, but these indications do not mean directly that visiting such a site installed serious malware, such as a keylogger or a Trojan?

[SAS Customer Service]

No, just that the low-risk items listed were put into the IE cache.

Thanks a lot for the help! Gotta love SAS!!
