Following an internet search for help I came across this forum. I have been working to clear VX2 for about a week with no joy at all. I had kindof come to the conclusion that the solution might be to 'disable' the rogue .dll files using the Properties and Security permissions tab as suggested, but your post made me have another go. Ive just run a sweep with Ad-Aware SE, and Microsoft AntiSpyware Beta plus. No sign of it on my machine to date - although Im sure it will sneak back! The proceedure I used was:
1.Boot in 'safe mode'.
2.Run Adware-SE to locate the latest mutations of VX2 (Ad-Aware-SE is good at locating the B****stards but not deleting them. The VX2 plug-in seems to have no effect at all.)Do NOT delete. If you do they will just mutate.
3. Open the Windows\System32 files (where VX2 hides..) and locate the offending .dll s.
4. Right click the .dll files and select the security tab. Select 'System' as you suggest and deny all access. This prevents them replicating or hiding in running memory.
5. Open 'Killbox' (you need to download this)and kill the offending files. Also run the Killbox Windows Temp file tool and delete all Windows Temp files(Just in case the Bl**dy VX2 is hiding elsewhere!)
6. Reboot - and its gone! for now....
One final suggestion. The VX2 files wouldnt let 'Killbox' delete them even when neutered, so I selected the 'delete files on system re-boot' option. This finaly seemed to work. Hope this helps someone..this thing was driving me CRAZY!!!!!!!!
