Symantec's Norton line of products is well known for providing key system utilities.
It includes some products, such as CrashGuard, which might not deliver as much as promised, and others with too many bugs.
However, Norton AntiVirus always has been a flagship product competing successfully with other market leaders such as McAfee, and version 4.0 is no exception.
The latest version of the popular virus-catching software installs smoothly, includes smart options and can update its library of virus 'signatures' from the Net.
The AutoProtect module offers automatic scanning options. You can scan files, for instance, when they are run, opened, copied, moved or downloaded, besides the usual scan when your PC boots up. You also can schedule complete virus scans to take place regularly when your PC is not in use.
To protect against nasty files from the Internet, you can integrate Norton AntiVirus with browsers such as Netscape Communicator to scan certain types of files upon download.
