I'm not sure what is happening--you've clearly got a significant problem
with the kinds of things this program is supposed to help out with.
Can I ask that you 1) go to Tool, check for updates to get the latest
definitions, and 2) restart your machine in safe mode, and do a full scan,
not the quickscan. Do multiple scans, until one comes through clean. I can
see that this will be a challenge in terms of time, but perhaps you can do a
first scan in the evening, and then another to run overnight or something.
The default action for a scheduled scan is to quarantine, I believe, but an
attended scan should leave you at a screen which gives you choices. And the
product ought to be able to remove everything it detects.
You may want to be prepared for one possible issue that can result from
cleaning a machine, as described in this KB article, which you can print in
case of need after a cleaning run:
