I've completed the 8 steps. I'm not getting the option to attach files so I may need to log out and back in. If so, I'll attach the logs in the next post to this thread. Stay Tuned... In the meantime here is some background info and what I need help with. Background --------------- I'm helping to clean my sisters computer. Had lots of viruses and malware on it. Their son installed BitDefender on it but hadn't cleaned everything so it kept reporting problems and BitDefender was interfering with MS Office 2000 (Outlook specifically). Current Status ------------------ PC is running well. The interference with Outlook 2000 disappeared after I deinstalled BitDefender ClamWin Antivirus reports clean Malwarebytes reports 2 registry key remnants that can't be deleted (always get Access Denied) SuperAntiSpyware reports clean CombFix and HijaakThis report BrowserHelperObject that can't be deleted either but the errant file it points to has been removed Issues/Problems still pending ------------------------------------ 1. ComboFix log and Windows Security Center still reports BitDefender as the Firewall and Antivirus "on record". I noticed CombiFix log reports this file: c:\windows\SYSTEM32\DRIVERS\bdfndisf.sys (BitDefender Firewall NDIS filter). BitDefender did not apparently deinstall completely. How do I restore these to Windows XP defaults (Xp firewall, no antivirus detected)? 2. How do I get rid of these last remaining registry remnants that I can't seem to delete? 3. Do you see anything else in the logs that needs attention or further removal efforts? Thanks in advance for your help! see attached. for some reason the button to "manage attachments" did not appear from the "infected computer" so I had to send the files to another computer and attachment them from there. That may be another remnant problem so if there is any ideas on what to do to fix that, that would be great! Thanks again!
