Are any of the prompts giving you the name of the virus?
It would be helpful to know.
Also, do you have access to another computer, and to a USB flash drive?
As far as 'slaving' the drive..wish it were as simple as plugging the HDD into another PC and cleaning it from there.
A slave Scan can be a very dangerous procedure if any Registry changes are made without addressing malware loading points.
Another setback is that the Windows File Protection feature is not used when scanning a non-active partition.
There was a time when slaving was a fairly common procedure, but no longer. Slaving scans are out of date when dealing with the current malware.
You need to fix this virus problem using using tools that are designed to get rid of it.
