Students
Students living in the residence halls and running a Windows computer will need antivirus installed in order to access the network. Students with Windows computers who are trying to access the wireless network will also need to install antivirus.
There are antivirus companies that will provide free antivirus software for non-commercial use. Examples of this include AVG antivirus, by Grisoft; Avast home edition by Alwil; Antivir personal edition classic by H+BEDV; or the open source project ClamWin. While Loyola does not endorse or support any of these companies, you should be aware of your options for free virus protection if you do not wish to purchase antivirus software.
Faculty and Staff
All Loyola computers should be running a copy Symantec antivirus, indicated by a small shield in your system tray 
.
If you are using a Loyola computer and don't have antivirus software running, please contact the Tech Support Center @ 4-4444.
For your home computer, you may qualify to be able to use one of the free packages listed in the Student section. The open source solution, ClamWin [link outside of LUC.edu], is a free option available to all. Alternatively, you could purchase antivirus software from a vendor at a local electronics store.
Updating virus definitions
All antivirus software makes use of virus definitions. These definitions allow antivirus software to recognize viruses. Since new viruses and virus variants are released almost daily, it is important to regularly update your virus definitions. Most software programs allow you to schedule updates on a daily basis, which we recommend.
Regular scans
Most antivirus software will allow you to schedule weekly or monthly scans. By scheduling scans at regular intervals, you better protect yourself from new viruses. If you receive a file containing a new virus before the virus definitions for your antivirus software are updated, then you may become infected by that virus. But if you scan on a weekly basis, once the antivirus definitions are updated to include the new virus, you will be notified of the infection and can take the appropriate steps to restore your system.
