I have a laptop with Windows 7 untimate. My computer was slowing and/or freezing really bad-- wasn't sure if it was some kind of malware or a problem with the computer itself. I did some work on it, and while it has stopped freezing, I am getting error messages in system restore and uninstaller so it looks like Windows has been affected. Here are the details.
-Computer would freeze after being on for a minute or two. Any open windows would work fine and then suddenly stop responding and I'd be forced to restart. (Even CNTRL ALT DELETE took several minutes to load).
-Ran troubleshooter through Windows and it said there were problems with the program in startup. I unchecked one that said (default) and one that said hpwuSchd application, both of which CNET said could be from trojans. Computer worked ok. No problems found by Webroot. However Malwarebytes would freeze while running.
-Computer worked fine for a few hours, but started to freeze again after sitting overnight. MSconfig kept freezing, Malwarebytes, SpyBot all would freeze a few minutes into running. Tried to download and run "Security Check." which also froze.
-Ran dskchk/r which said it fixed one file. Ran rkill and then was able to run Spybot and Malware but they didn't find any programs. Ran CCleaner to delete temporary files, etc.
-Computer appeared to be working ok, so i tried to create a restore point in case I run into more problems and got this message. "There was an unexpected error in the property page. The volume shadow copy service used by system restrore is not working. For more information view the event log. (0x81000202)"
-Tried to uninstall some unused programs and got this error message. "Windows installer service could not accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance."
Did I somehow mess up Windows when I ran the other programs? Could there still be some malware on there? Did I do more harm than good?
Also, I am unsure whether this should be a virus issue or a windows issue, so feel free to move this topic as needed. I originally had a topic open in "Am I infected?" but said to close it once I thought I figured out the issue. (Looks like I didnt... (sheepish). ) Thank you so much for any assistance!
