Setting anti-virus policy

13

Administrators can standardize virus protection settings over the network 
by locking configuration settings on the Norton AntiVirus clients. Network 
users cannot change settings for locked items. By standardizing virus 
protection settings, an administrator can protect the network against virus 
invasions without slowing the normal performance of the network. 

Setting anti-virus policy

Norton AntiVirus provides two types of protection: File System Realtime 
Protection, which constantly monitors files for infection as they are 
accessed or modified, and scans that can be initiated on demand, 
scheduled to run unattended, or invoked automatically at system startup. 
In both cases, there are two basic configuration components:

What to scan

What to do if a virus is detected

Choosing what to scan

Norton AntiVirus File System Realtime Protection scans all file types by 
default. Manual, scheduled, custom, and startup scans also examine all file 
types by default. You can choose to scan files by file extension or by type 
of file (documents and programs) but your protection from viruses is 
reduced.

What to do if a virus is detected

Norton AntiVirus responds to infected files with actions and backup 
actions. By default, when a virus is detected by either Realtime Protection 
or during a scan, Norton AntiVirus attempts to clean the virus from the 
infected file. If Norton AntiVirus cannot clean the file, the backup action is 
to move the infected file to the Quarantine so that the virus cannot spread.

Depending on your anti-virus policy, you can change these settings to 
delete on detection or leave alone (log only). For File System Realtime 
Protection, you can also choose to deny access. In addition, you can set 
different actions for macro and nonmacro viruses for each scan type 
separately.
