I've dloaded the Farbar Scanner Tool onto a thumb drive and tried to run it but no programs will run or install, even programs on the computer already. The computer is ungodly slow to even get to the point of getting to programs.
When I could get to the programs I would try to left click and Run as Amin but would get the same error for every program already on the computer i.e. file system error (-1073741819).
I quarantined 6 PUPs in Malwarebytes but was unable to find anything else?
