I wonder if you could help me with this retro-problem. I say retro because out of lack of time I had to format the computer. Still, I wonder what malware I had and what is the solution for it's removal.
A computer was brought to me with a screen-wide message, yellow on blue, which told me (I don't remember the exact text) that I spyware was discovered and I need to install an antispyware program (not a specific one).
The computer would boot up to the logon screen and when I logged this message would show up, covering the entire screen for 30 seconds or so, the computer will start a log off and go back to the log-on screen. This exact phenomena happened in safe mode, last good confuguration etc. No way to boot up.
I rigged the hard disk to another computer and in safe mode ran AVAST, AVG Antispyware, Spybot. AD-Aware, AVG free antivirus anf a 19 days trial version of Kasperski. There were lots of high-risk malwares of all strips. However, the particular one was not found and removed. I still couldn't boot. Eventually I clean formatted.
I searched on the net but couldn't find any solution. The problem, in a minor version, is familiar but not on the scale I am talking about, which prevented me from any form of booting up.
Any one knows what the problem and solution are?
Thanks in advance.
