how recently did you uninstall AV?
As opposed the the virus vault, do you have the option to clean, disinfect, remove, reapir this virus?
Ok, start by going to start, run, type msconfig hit enter
-go to startup tab and look at the programs in the list
--do you recognize each one and what they are, if not you can search google to find out what they are related to or post them here
I would download and run malwarebytes free version to see if it detects anything and help remove things it does find
Malwarebytes.org
Paid version offers:
Activating the full version unlocks realtime protection, scheduled scanning, and scheduled updating
So use it to scan manually and see what comes up
start with this and post back
