I have a relatively new Vista box (trying to find a weekend to upgrade to 7) that I've kept up to date with all windows updates. Running the firewall and MS's Security Essentials.
I was checking network traffic in Resource Overview and I have an entry for svchost sending data to the address of 'kuk'. I also have another svchost sending data to an address of my username. I assume/hope 'kuk' is some sort of system account? Googling it led to a few pages that referenced a virus but only in the context of there being some 'kuk.exe' file quarantined by virus scanning software.
Some more details from Resource Monitor:
Image: svchost.exe (NetworkService) PID: 1392 Address: kuk
Regarding the thought that it may be a trojan, I just ran a full scan with MS's security tools...nothing found. This machine isn't used heavily. It's mainly my dev machine. So I haven't been downloading random stuff. Any suggest additional scanning software for Vista (and/or 7?)
