well as damage data, delete files, and even completely erase your hard 
disk. Macro viruses, the newest threat, infect and spread throughout 
Word and Excel documents.

Whenever an infected program is run or an infected document is opened, 
the attached virus is activated and spreads to other programs and 
documents. Viruses don’t, however, infect or damage hardware, such as 
keyboards or monitors. You may experience strange behaviors (such as 
characters appearing upside down) but your disks are not physically 
damaged, just what’s stored on them.

Norton AntiVirus safeguards your computer from virus infection, no 
matter what the source. You are protected from viruses that spread from 
hard drives and floppy disks, those that travel across networks, and even 
those that are downloaded from the Internet. In short, Norton AntiVirus 
does the following:

■

Eliminates viruses and repairs virus-damaged files.

■

Makes sure your computer is safe from viruses at startup.

■

Checks for viruses every time you use software programs on your 
computer, floppy disks, and document files that you receive or create. 
(For example, the newest kind of viruses are spread via Microsoft 
Word and Excel macros.) 

■

Monitors your computer for any unusual symptoms that may 
indicate an active virus.

■

Runs a scheduled scan automatically once per week to confirm that 
your hard disks are virus-free.

■

Protects your computer from Internet-borne viruses as part of regular 
operation. No separate programs or Norton AntiVirus options 
changes are necessary. Program and document files are scanned 
automatically as they are downloaded and files within compressed 
files are scanned when they are extracted.

Once a month, obtain from Symantec updated information that Norton 
AntiVirus needs to keep your virus protection up-to-date. You can do this
