After some virus had infected my Windows 7, I did a complete format and re-installed the OS. I was just installing applications and copying back some data when I noticed some shortcuts changing their icons to something I couldnt recognize (Yellow icons in the image below).
Also, a few exe files which previously did not ask for User permission, are now asking for it.
Wondering if this is an icon cache problem, I cleared the cache by deleting the
IconCache.db in AppData/Local but the problem still persists.
Although I did a full system scan with MS Security Essentials, I'm not sure if this is another virus or some other problem. I would appreciate any suggestions you might have.
Edit: Now even Firefox needs permissions to launch. It's icon hasnt changed, but it's got the 'shield' overlay on it like the other yellow icons.
Edit 2: Now some applications are not launching anymore. Picasa, Foxit are not only causing problems in launching, but arent getting uninstalled properly even. I guess its surely a virus now.
