How do I remove a virus from my computer?
Tip: If you're concerned about a specific file being a virus, see our verifying if a file is a virus document.
Virus detection and removal
If you believe your computer is infected with a virus, the best method of detection and removal is to run an antivirus scan on the computer. Open your antivirus scanner through the Windows notification area or through the Start Menu and run a full system scan to scan all files on your computer for a virus.
If you're unable to boot into Windows, boot the computer into Safe Mode and run the scan from within Safe Mode.
Removing detected virus
If the antivirus program detects the virus, a prompt to either move the virus to the virus vault or delete the infected files will be given. Both options are a good way to remove the virus from the computer.
I don't have an antivirus program installed
If you do not have an antivirus scan, but still believe a file is infected with a virus, try running an online virus scan. These websites will scan your computer hard drive for any infections. You may also consider installing a free antivirus program on the computer.
Note: It is not recommended to manually find and delete files on your computer that you suspect to be infected with a virus. You could delete files that are not infected with a virus or related to a virus, which could result in errors on your computer and possible issues with the operating system loading and running properly.
No virus has been detected
Unfortunately, many non-virus related issues are often blamed on computer viruses. Nine times out of ten, a computer problem is a software, driver, or hardware related issue and not a virus. If after running the antivirus, no virus is found, it's very likely the computer is not infected. If you still believe your computer is somehow infected, you may also consider running an online virus scan and scanning the computer with a malware protection program, as mentioned below.
