If your computer is running slowly, or it isn't performing as expected, it may be infected with malware or a virus.
The following are directions for removing malware and viruses from your computer, and/or closing major security holes in your operating system. Please pay attention to the order in which you perform these steps; performing them out of order may cause problems.
IMPORTANT! If you suspect your University-owned computer is infected, STOP. Do not attempt to remove the virus or shut down your computer. Because this may constitute a data security incident, contact your IT Administrator or the OIT Help Center immediately.
Note: If your network connection has been turned off due to virus infection or detected vulnerabilities, please visit or call the OIT Help Center (A109 LGRC Lowrise• 545-9400) when you have finished these steps for disinfecting and/or removing vulnerabilities from your computer.
Before you can begin fixing your computer, you have to obtain the necessary files (below) and print this document. Your computer will not be connected to the network while you are disinfecting it, so you will not be able to access these files on the Web.
Note: Even if you already have McAfee VirusScan installed, uninstall it, then download and install the latest version.
You can also get these instructions and software on CD from the OIT Help Center by going to A109 LGRC Lowrise with your UCard. Each CD costs $3 and includes additional malware removal software and Windows updates not available directly from the OIT Web site. You can also download an .iso image of the CD free of charge and burn it to disc yourself:
An ISO Image is similar to a zip file in that it groups several files into a single download that is easier to manage. When you burn this image to a CD, it produces a full copy of the OIT Anti-virus CD from which you can install the software and updates you need to disinfect your computer. See Burn a CD in OIT Computer Classrooms for more information.
Remember to print or save this document!
Your computer should not be physically connected to a network (e.g., cable modem, DSL, UMass Ethernet). Unplug your network cable from the Ethernet or phone jack and do not reconnect it until you have finished this process.
To effectively remove viruses, make sure you do not have other anti-virus applications (or previous versions of VirusScan) installed on your computer.
The anti-virus software provided by OIT comes with the latest virus updates and definitions.
This update ("SP3") includes significant improvements to the security of the operating system and network software such as Internet Explorer and Outlook Express. You can download this file from the Microsoft Download Center or you can get it automatically through Windows Update (windowsupdate.microsoft.com).
