This page explains what to do if you think your computer may have a virus. These instructions assume you are running Windows — if you are running MacOS and believe you have a virus, please contact the IT Help Center.

Special Case: Have you been notified by BU’s Information Services & Technology that your computer may have a virus, or has your BU network access been disabled because of a virus? If so, you should have received email describing the specific steps you must complete to be put back on the network. If you cannot locate this email, please call the IT Help Center at 617-353-4357. We can look you up on a list and tell you why your network access was disabled and exactly what you must do to regain access.

If you have not been notified of a problem, but you think your computer might have a virus, please read on.

1. Perform a system scan with the BU VirusFix/Security tool

Information Services & Technology has created a simple BUVS tool that will scan your computer for viruses and help you remove any virus infections. The tool also prompts you to change your Windows Administrator password and sets up Windows automatic updates, if your version of Windows allows this. When you finish running the tool, please come back to this page.

2. Update your anti-virus software

The BU VirusFix/Security tool removes existing viruses but it does not provide continuing protection against viruses. Once the virus has been removed, you should make sure that your anti-virus software is up to date, and set to download updates automatically every day and scan your computer at least once a week. If you do not have a current anti-virus program, you can download McAfee VirusScan, for free, as Boston University has site licensed this package.

3. Make sure you change all your Windows passwords.

The BU VirusFix/Security tool prompts you to change your Windows Administrator password. You may have other accounts set up on your computer with Administrator privileges, and you should change these passwords yourself. You may wish to change your BU (Kerberos) password as well.
