Hi Broni: I followed yor reccomendations to the letter. I disabled the AVG Antirus,and started running ComboFix.
It started running,and asked me,if I want it to install the Recovery Console,I said yes,and then all of the sudden,the scan stopped,and the Screen turned Blue,with this message: "A problem has been detected and Windows has been shut down to prevent damaged to your computer..........
I tried to restart the PC on Safe mode,but the same blue screen appears!

Any suggestions?

Thanks!
