Of late I have been getting the above error message on this computer - Window XP Home.
I have trawled the net only to find the most relevant thing being for Visual Studio 2005. I looked on MS knowledge base for a solution, did the necessary updates and patches. But I still keep getting the above error.
I have also conducted a full and deep scan with anti-virus, spyware, maleware, check the event viewer still nothing.
Well what a pa-larva last night. I ran Stinger and it got rid of the virus/hacker (Qttask.exe). I rebooted only to find that it was back again. I re-ran Panda and my malware programs and it was still there. I then tried CWshredder, which advised me to install a new version of the program to get rid of the virus/hacker. This found it straight away and I was able to delete it. To double check I re-booted only to find it back again.
I then asked my sons if they had been on the computer. One of them admitted to opening a port on the router so he could download a movie, AAARRRGGHH!!!!!
Port closed now and an encrypted password on the router this time.
