Open the Symantec AntiVirus window by double-clicking on the following icon in the system tray, at the lower right corner of your screen:

On the left side of the window, click on "Full Scan":

Then click on the "Scan" button, in the bottom right corner of the same window, to begin the scan.

The scan may take a while, but if the window is minimized, the computer can be used normally while the scan is running. 

 * 

If evidence is found on the university network that a computer is infected by a virus or worm, that computer is disconnected from the network and the registered user is notified. 

*

A full scan of your computer (see above) may find and "quarantine" one or more viruses.  When a virus is quarantined it does not remove the virus from the computer, it only renders it harmless.

*

In either case, it is necessary to remove the virus from the machine immediately. 

Symantec, the University's vendor for Antivirus software, provides removal tools for most major viruses, which can be found by clicking here.

Note: Most removal tools are specialized for a specific virus or worm.  Be sure you use the correct tool. 

 * 

For widespread infections on the University network, CDs may have been prepared with removal tools.  Call the Help Desk at (212) 960-5294.

If there is not a CD available, you will have to go to an uninfected machine and download the removal tool(s) to a floppy disk, zip disk, or memory key, and then use that to run on the infected machine.
