Need Help Mystery Bug

I've not seen that before but I have seen malware which adds some dodgy DNS servers to your network settings.

Are you using DHCP ?

Yes, I was using DHCP. It did change my DNS server, too. It seemed to move across my network to my other two computers, both of which had firewall, AV, and active anti-spyware running. I was using NIS 2007 on one and Zone Alarm Security Suite on the other, all kept up to date.

It changed the third octet from the default .0 to .15 on the individual IPs, default gateway and dns server.

I had to manually change the TCP/IP settings from auto to static using the former default IPs and unused client IP. The closest thing I've been able to find was some form of Sasser worm?

My email provider has good Kaspersky AV protection, and although possible, I have a hard time believing it got past that and the security on my PCs. I'd like to be able to pinpoint how it got on my computers and if the damage is only annoying or if it is actively stealing personal data.

pcjum - I don't use AOL. The only masking app that might do something like that is a feature from NIS 2007? This did it on its own out of the blue and from nothing I did manually. I did reset the router and even flashed it to the latest firmware. I ran MS malicious software remover, all NIS scans, loaded AVG and scanned, Ad-Aware, Spybot, and they all came up clean.

The one thing I haven't tried yet is using BartPE and run an AV scan with that. I've never used BartPE and not sure if this would even make a difference.

Thanks for the replies.
