Last night I shut down my Internet connection and ran Webroot as I turned in. This morning it said no threats were found.
I ran Spyzooka this morning, first thing, and it found four threats -- two tracking cookies, two registry entries. The registry entries said:
W32 Worm AutoIt [Trojan Horse]
Registry
W32 Trojan-Proxy MSIL [Trojan-Proxy]
Registry SOFTWARE\\Microsoft\\Security Center\\UacDisableNotify
When I clicked Take Action, it says to remove W32.Worm.AutoIt to reboot and run Spyzooka in safe mode.
Guess I'll have to email Webroot, but I don't think one product ever is enough.
