I have a strange one that I haven't come across yet. A computer with Windows 7 Home Premium x64 started having a problem yesterday with exe files (I think). Most (but not all) exe files won't open.
Example - when I try to open Firefox, either from the desktop shortcut, or from the exe located in Program Files (x86) \ Mozilla folder, the following message appears: "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."
also, the icons for the files I can't open have been set to generic icons. I've checked/changed permissions and taken ownership, in case that helped, but it didn't change anything, the weirdest things are:
1. Some exe files and programs will open - for example, mahjongg won't open, but spider solitaire will. in the case where the program will open, the icon is in tact.
2. everything works perfectly fine in Safe Mode with networking - i can open firefox, surf the web, download files, everything I should be able to do.
What I've done so far -
--> downloaded, updated and ran Malwarebytes Anti-Malware, found a few infections (although I think nothing major)
--> disabled all startup items and (non-microsoft) services
--> i tried to run hijack this, but when i tried to install it to "C:", it gave me the error that it must be installed on a local volume
--> i did head into the registry and check the exefile and it was set properly under HKEY_CLASSES_ROOT
I don't think its a virus issue, but I'm totally stumped on this one, anyone have any ideas? I don't want to reformat if I can help it.
Thanks in Advance,
