From Last one week I face a new Problem in My PC. Every time when I insert a new Pen Drive or any storage device/Hard Drive then it Shows Top of the Right Menu. When I Double Click ON the Drive then it Shows Error "Application Not Found". I still not Understand Its a Virus or anything else because I full scanned my PC with Avira Internet Security 2012 & Kaspersky Rescue Disk but Not Found Any Virus in my PC.
I find it hard to read the .jpg run maleware bytes and post the report here, this could be just simple rather than a virus.. maybe you have disabled a service...
If I am not wrong, there is an autorun.inf file that is commanding Windows to launch a file that is already deleted whenever you double click on the drive.
Hit WIN+R which will bring up the Run window.
Type cmd in the box and hit enter. That should launch a black window called Command Prompt.
Type the following command replacing the X with the drive letter of your USB drive: type X:\autorun.inf
Do let us know what you see.
