My system was running like a dog and intermittently crashing. I'm still using Xp with SP3. Symptoms Firefox randomly crashing and occaisionlly the blue screen of death. Downloaded the recommended SW from the stickie, ran some tests found 3 objects which Mal ware bytes has got rid of. Files Detected: 2 C:\WINDOWS\KMService.exe (RiskWare.Tool.CK) -> Delete on reboot. C:\Documents and Settings\Ruth\My Documents\Downloads\Miro_setup.exe (PUP.BundleInstaller.OI) -> Quarantined and deleted successfully. A residual problem that I have noticed is that add and remove programs won't populate. I downloaded tweaking.com_windows_repair_aio_setup.exe. AS I bought the PC off ebay I don't have the Windows disk so can't run the system repair test. I've also found that the system is running a bit slower still - any ideas - Could I be I still infected?
