The customer can modify these settings, but IT recommends customers leave these three scanning methods active. Although the virus program will protect against viruses in general, it needs to be updated regularly to be able to locate and eliminate new viruses, or versions of the same virus. Even older viruses can cause problems, even long after they cease to be perceived as a threat.

The software is being distributed set to automatically check the UH redistribution site, but customers might want to check periodically to ensure they are using virus definitions that are no more than one month old.
Customers can then compare any symptoms they are having with the listed viruses.
