VirusScan offers the chance to scan a suspect hard disk before installation; scans are fairly quick. Unfortunately, the default installation is with floppy scanning off. This leaves the computer vulnerable, although the settings are easily changed. Scanning Internet files requires the optional WebScan software.
VirusScan is priced at pounds 29 (ex VAT). This includes one free online product update and BBS for the first 90 days, with an option to purchase a personal maintenance plan or quarterly disk/CD-Rom updates.

Norton AntiVirus and Symantec AntiVirus for Macintosh (SAM) are twin products from Symantec. Norton is more sophisticated than SAM, with live updates of the software over the Internet. This overcomes the problem of virus software becoming out of date.
Norton for Windows 95 includes a separate emergency disk for scanning. SAM and Norton for DOS/Windows check for viruses as part of installation. SAM and Norton AntiVirus for Windows 95 both scan Internet files automatically. The packages also automatically prompt users to set up software options properly, as part of the installation process.
Norton AntiVirus for Windows 95 is priced at pounds 69, pounds 99 for Windows 3.1. Symantec AntiVirus for Macintosh costs pounds 69. All prices are exclusive of VAT.
