I am already running the most up to date Windows Defender firewall, but got careless and allowed this process in as three things naming themselves with 'vista' and 'Windows' in the title popped up. In retrospect, of course I realize that nothing that was actually from Windows would have triggered the firewall's alert.
I have purchased MalwareBytes recently and when scanning it says that the problem has been quarantined and removed, (C:/Windows/svc.exe) , but additional scans after restarting my computer as directed show the same thing as being infected.
I've run rkill several times to try and remove the problem in conjunction with MBAM and Windows Defender, with no success-and am on the 3rd downloading option on this site's list, as the first two seem to be recognized by the virus now.
I've managed to create a flash drive that my computer can boot to (at least the dialogue box said it was a success), but have either not been able to boot it succesfully so as to remove the virus, or I simply cannot do so.
Furthermore, my computer has an odd quirk (not a recent development, this has happened since its purchase) that will not run system repair when my computer has shut down unexpectedly- it simply doubles back to the option screen until I select 'Start Normally'.
I very much appreciate you taking the time to help dig me out of the 'hole of dumb' I've dug for myself.
Thank you very much for your help, and have a warm winter,
