On my 2nd Dell a gaming PC, running under xp sp3 there is a "parasite" which is detected only by the real time Block as : RKIT/INJUNK.A.|[TROJAN] C: \windows\system32\Msvtx86.aqmgu The Avira scan does not detect this but the block does. No matter what he does quareenteen, deny etc the issue keeps recurring. A number of BSOD's have also occurred. As well the message NT services has encountered a problem and must shut down. It seemj clear the block can detect but not remove this one. He did run SAS and it found 9 issues and fixed them but this one remains. 3 files in systems 32 folder: msvd86.agmmgu msvp86.agmmgu msvk86.agmmgu He deletes manually but they keep getting recreated. This is a bad one! Any clues/advice before we reformat the PC from scratch? I'm particularly interested in hearing from anyone who has hit this one with Avira.
