Registry viruses can cause varying degrees of harm to the computer.

Viruses in the registry, as well as the memory and file system structure of a computer, can eventually spread, and catastrophically and adversely affect the performance of software, files and devices connected to the computer. Detecting viruses as soon as possible decreases the risk of irreversible damage to the system registry and prevents viruses from replicating to other areas of the computer and causing the same potentially irreversible damage.

Open the antivirus program either by clicking the Start menu and clicking on the antivirus program or clicking the desktop icon to open the antivirus program.

Use the appropriate menu options in your antivirus program to set the scan settings for the scan you are going to initiate in Step 3.

Use the option to scan for viruses in the registry if you only want to scan the registry without scanning other areas of the computer such as the hard disk and memory.

Click the option to begin the scan. The amount of time required to complete the registry scan and detect viruses will vary depending on the speed of the processor of the computer as well as the number of items included in the registry.

Upon completion of the registry scan, you will be presented with a list of the items in the registry that were found to be infected with viruses, if any. While some antivirus programs such as AVG Antivirus will remove these items automatically, you should still manually delete the infected items once the scan has completed. Choose the option on the antivirus screen to remove the items after the scan has completed.
