I am not one to open attachments, and I didn't. I don't hang around in obviously infected websites. But, during a flurry of Google searches and research on carbon monoxide detectors and meters,
I run ESET Business Edition on my computer for Real Time scanning and weekly scans. It also, obviously, detects malware as they occur, although it didn't detect this. I just happened to have MBAM running (not doing any real time scanning or scheduled scanning -- just there).
It started blocking multiple attempts to access the Internet to sites which were in Russia. I disconnected it from the network and ran MBAM, SAS and ESET scans, all of which only found PUPs.
I have not tried any root kit scans. I am not sure what to do next. This is Win 7 Pro on a domain run by SBS 2008.
Any help would be appreciated.
