How can virus be eliminated from the System Protection (Windows 7/Windows Vista) or System Restore folder (Windows XP)?

Information applies to:

Products
All products

IMPORTANT: Remember that you should only follow these steps after disinfecting the computer. These instructions alone will not eliminate malware.

Symptoms
Sometimes, even after viruses and other threats have been disinfected, the antivirus may still detect them again and again in the System Protection (Windows Vista/7) or in the Restore (Windows XP) folder without being able to eliminate them.

Cause

Although malware is detected in these folders after disinfecting the computer, it does not mean that the computer is still infected. This situation, created by a particular characteristic of Windows Vista/7/XP, is not dangerous at all, although it may worry some users who are not familiar with the use of these folders. Windows Vista/7/XP offers the possibility of restoring the system automatically, recovering eliminated files or system settings accidentally modified but its contents cannot be manipulated by anyone or anything.

This feature, although sometimes advantageous, may cause the following conflict: when the antivirus performs a scan, it will detect the infected and the erased files in the System Protection/System Restore folders.

That is why when a new scan is performed, the antivirus will keep on detecting the file in those folders but won’t be able to eliminate them, as the file is protected by the operating system and is out of its reach. Therefore, you will need to delete them manually by disabling and re-enabling System Protection/System Restore feature.

Solution

Find the solution to apply according to the Operating System of your computer.
