OT: Microsoft is really annoying

Hi Wilhelm. 

I checked the URL with our corporate content filtering system and it came up clean, so the site seems reputable. However, I just read an article about how reputable sites are getting compromised, and either a redirect is put in place, or the site itself is being compromised. Simply visiting a compromised site can infect an unpatched machine. So it does not surprise me that your visiting a reputable site resulted in an infection. What DOES surprise me is that your antivirus (assuming it is up to date) did not catch it. Perhaps this happened before you installed the antivirus? 

The hsyfea.exe looks like a random file name, which was typical of a particularly nasty bit of malware I came across a while back called coolwebsearch. The installer installed several variants of itself using random file names, which required a program called HijackThis and a series of safe boots to remove the hijacker. Even then, with some flavors of the "adware" you never got all the pieces, and the recommendation at that point was a clean reinstall. 

The other one turned up some interesting google hits. I believe this to be a particularly nasty one, but if your Antivirus found it, then it should have prevented it, unless as I said, you got it before you installed Antivirus. If you got it first, then there is a possibility it installed a rootkit, in which case nothing but a wipe and reinstall to a new partition, and to be safe, a reset of the CMOS first, will guarantee it's removal. 

My condolences. 

Bob

I did not download anything from the TwistedBrush site. This happened twice, I will not test this a third time. Maybe anybody else could check?
