This happens because some malwares creates a file "autorun.inf" in the root of every drive to execute the malware exe every time a user double click to open it. Now the malware is gone but the inf file is still there. "Autorun.inf" itself is not malicious. Removing that file from root of every drive will solve the problem. Follow my instructions.
A ) Show hidden and protected files.
- Click Start, and then click My Computer.
- On the Tools menu, click Folder Options.
- On the View tab, click Show hidden files and folders.
- Clear the Hide protected operating system files (Recommended) check box. Click Yes when you are prompted to confirm the change.
- Click OK.
B ) Now open "My Computer" in explorer mode. To do this either right click on the "My Computer" icon and choose "Explore" or press the short key combination "Windows key+E ". You can also open Windows explorer via "Start-->Programs-->Accessories-->Windows Explorer".
C ) Now open the volumes from the left side pane of the explorer window. (don't use the regular double click opening)
Delete the file "Autorun.inf" from the root of every drive and restart the system.
Make sure to install a good antivirus and do a full scan. If you can't remove the virus by using regular antivirus programs, post a malware removal help request in the "Malware" section of this forum.
