Was given to sort out a Toshiba laptop with Win 7 64bit loaded but its silly owner had not activated Nortons that came with its software package, also had Malwarebytes but just the freeware version so not active.
Yes you are right tons of malwares and trojan while watching the cpu graph it looked like a picture of a saws teeth with the cpu running at about 60%.
I have hit it with Malwarebytes, Avast, CCleaner, sfc scannow check/scandisk with full checking several times and it has become a quiet system but I am unable to get it to enter Safe Mode.
It can get to the sign in stage, you click to enter and about 5 seconds later it resets to boot all over again, though I did see a message flash that there was not enough resources before re booting. Under sfc it said that some files could not be repaired.
Am I looking at a re-install but worry if I use the transfer wizard it may carry some hidden error over to the new installation.
Any ideas please....
