Dear experts, i am having problems regarding my pc boot as well as virus/malware detection issues. win logon.exe bad image pops up before my pc reaches windows screen. 1. Winlogon.exe bad image "The application or DLL C:\WINDOWS\system32\KBDUS.DLL is not a valid windows image. Please check this againts your installation diskette." *I click OK and i am able to reach windows. 2. I took a scan for my computer using avira and has 4 detections. but it seems no action was taken? last detection was a BOO/TDss.m . I have attached the latest report file and it says "action taken: ignore" but as i could recall, it never did give any other option but End and REPORT. how can i get rid of these problems. i must say that i am not that familiar towards this subject matter as it seems to be complicated. your step by step instruction would be greatly appreciated. THANKS.
