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. Update and scan with your anti-virus software

Make sure that your anti-virus software is up to date, set to download updates automatically every day, and set to 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.

2. Make sure you change all your Windows passwords.
