My pc started having problems playing dvds. After installing WinTop, I discovered the problem appears to be a program called winkblr.exe. It's a major resource hog -- using up to 90% of available CPU power. A search of the MS knowledge base didn't help identify the file and, according to msinfo, winkblr.exe is not a Microsoft file. I am unable to "kill" this program. First, it doesn't appear among the active tasks in the task monitor, so I can't stop it that way. Second, I used msconfig in an attempt to prevent it from starting, but it started anyway! Third, I tried to delete or rename the file, but windows won't allow that. Fourth, I found its run command in the registry and attempted to delete it, but windows wouldn't allow that. 1) Can anyone tell me what this program is? 2) How do I stop this program from loading?
