OIT Home > OIT Knowledge Base Search Knowledge Base: My computer says I have a virus, what do I do now? First, make sure that your antivirus product is as up to date as possible. If you are using UT's antivirus product Endpoint (available from http://antivirus.utk.edu), you can get the latest definitions by using Microsoft Updates. If you are using Microsoft Security Essentials, go to the Update tab and select the Update button. If you are using ClamXav for Macintosh computers, select the Update Virus Definition button on the main ClamXav window. Next, begin a full system scan. This will search your computer disk and memory for malicious programs and delete or quarantine them. In Endpoint, a full scan can be initiated by double-clicking the green Endpoint icon on the lower right portion of the task bar and then selecting the Scan button. (If the Endpoint icon is red, double-click the icon and then select the Smart Clean button. After the Smart Clean is finished, you should complete a full scan.) In Microsoft Security Essentials, a full scan can be initiated from the Home tab by placing a mark in the bubble next to Full Scan and then selecting the Scan Now button. In ClamXav, a scan can be initiated by selecting the Start Scan button on the main ClamXav window. After your scan is complete (it could take several hours), if any viruses were found it's a good idea to reboot your machine and scan again. It is also a good practice to schedule regular scans, either weekly or daily. If your virus problems are persistent, please contact the HelpDesk. Students can also bring their computer to the OIT Service Center in the Hodges Library Commons for assistance.Need more help?
