I am getting a message indicating that Isass.exe Application Error on a black screen and nothing else. Attempted to start in safe mode...."safe mode" in four corners but can't go or do anything else. I had a message indicating a threat and removed it to the vault. System shut down and I can't seem to get back in.....what do I do now?

You are more than likely infected. Safest way now is to Slave your HD to another HD/comp ( no need to bolt it in, just cable it & leave it outside the case ) You may have a choice of jumper settings on the master HD, such as master with slave or ms. Run it's virus program on the drive. You should also run these 2 programs. Update after installing.
