Recently, while trying to open my calculator on my Laptop i noticed the error "windows cannot access the specified device path or file". I also cannot open my task manager. I have fooled around with permissions and junk but im not really sure what im doing. I recently downloaded HiJackThis and I have a log of my stuff. I dont know if theres anything in the log I need to fix or not to help repair this problem but it couldnt hurt to post.

You are infected with the explorerr.exe trojan . See this page . Download and run Malwarebytes to remove. Jerry

Thanks for helping me get rid of that virus but im still getting this error? :(

Try doing a system restore to a date a couple of days prior to experiencing the problem. Rerun Malwarebytes after the system restore to be sure it didn't re-introduce the virus. If that doesn't work, try an upgrade reinstall . Jerry

I can't! When i try to run the system restore i get the same error. "Windows cannot access the specified device path or file for Windows 7" This sucks. :(
