Do I Have A Virus?

The only sure way to know if you have a virus is to scan your computer with an antivirus program with up-to-date virus definitions. If you don't have an antivirus program installed, or if your antivirus program is being disabled for some reason (viruses can do this!), try one of these resources:

  • MalwareBytes Anti-Malware (free version) - The free version of MalwareBytes is one of the best tools to find and remove viruses from your Windows computer.
  • Sophos for Mac Antivirus - This free for Mac antivirus program will proctect you from viruses that try to get on your computer, and can find and remove any viruses that are already on your computer by running a scan of your computer.
  • If you detect a virus, try to remove it with the scanning software. If the virus can't be removed, see our How To Remove a Virus page.

If you encounter, or suspect, a virus you are encouraged to contact the IT Service Desk.

Below are some possible virus symptoms. Any of these symptoms could also point to problems with the operating system, software, hardware, adware, and/or spyware. Still, here's the list:

  • Your computer is noticeably slower than it used to be, or seems to be busy doing something else.
  • Your network connection is slower than usual, or seems really busy (this can just as often be the network or ISP).
  • Your computer freezes or crashes repeatedly.
  • Your antivirus program stops running without an error message.
  • You notice strange processes running on your computer (this assumes you know what the usual processes are).
  • Folders on your computer start sharing themselves across the network.
  • Files start appearing on your hard drive, perhaps in multiple locations.
  • Microsoft Word or Excel suddenly start warning you about macros existing in your documents.
  • Whenever you are browsing the web you consistently get pop ups and advertisements on your computer.
