I have a desktop that is deeply infected. Cannot verify that it has done so, but it appears to be bypassing MWB Pro somehow.
I would like to create a vaccinated USB drive with this computer to run AV software from, but considering it was on a HomeGroup (that I DID NOT setup) w/ the desktop, I can't be certain it isn't infected.
For this laptop, symptoms include randomly unresponsive trackpad, general slowness that does not match its age/use pattern, and booting up at night despite being set under power mgmt not to do that for any reason.
I've scanned w/ MWB here (not pro, though that shouldn't matter) and ESET to no avail.
Please advise as to the best course of action. Thanks.
