Spyware doctor antivirus kept malicious application Explorer.EXE with path c:\PROGRAMDATA\_QBOTHOME\_QBOTNTI.EXE from going further, but the nest popup from explorer browser opening is paypal home page, and both keep trying and overload any other application. Ran Adawre.se, Registry Mechanic, now running full Spydoctor scan..kind of stuck at 22% scanned, can still run from safe mode with networking. will nest try Norton security and Mchaffee[sp?] but have to allow some type download activeX I believe, and it's disabled in safemode. any help is appreciated
