Yes.  OSU has a site license for McAfee VirsuScan.  You can download and install the software from the OSU Site License Site here.

If your computer came with a 'trial license' of anti-virus software, be sure to see when it expires.  At that time or before you'll need to either purchase a new license or install additional anti-virus protection.  If you decide to use your own anti-virus software, make sure it is configured properly.  Check the manual for instructions on how to make the following adjustments:

• Should check DAT file (virus update files) on a daily basis
• Should search for viruses upon opening or executing a file
• Should scan daily
• Should check incoming mail. (For those using Eudora, the configuration information is provided  here.)
