Impact of Virus-Related Problems

Impact of Not Installing an Anti-Virus Program

Anti-virus programs protect your PC from viruses, worms, and other malicious programs. Without an anti-virus program installed, your PC is vulnerable to infection.

Impact of Not Enabling Your Anti-Virus Program

Installing an anti-virus program isn't enough. It must be enabled to work. Until the anti-virus program is enabled, your PC can still be infected by computer viruses.

Impact of Not Keeping Virus Definitions Up to Date

An anti-virus program cannot protect a PC from the very latest viruses, worms, and Trojan horses unless its list of viruses is kept up-to-date. Until the newest virus definitions are downloaded and installed, your PC is vulnerable to infection.

Impact of installing More Than One Anti-Virus Program

When you have multiple anti-virus programs on your PC, they can interfere with each other and may result in a situation where your PC is being unprotected. For maximum protection, you should run only one anti-virus program at a time.

Impact of Not Regularly Scanning for Viruses

If you don't regularly scan your computer for viruses, new viruses can infect your system without you knowing it. To protect your PC from infection, your anti-virus program should be run regularly and frequently — at least once a week.
