Antivirus software protects your PC against viruses. The program scans the files and email messages you receive and warns you if they contain a virus. The program also tries to delete any viruses found.
Choose a recent program that scans files from both the Internet and email. Choose the program setting that automatically scans files all the time and not just when you start the PC.
Regular updates
These programs can protect only against viruses that were known before the latest update. You should therefore configure the program to update itself automatically or perform a manual update at least once a week.
Automatic subscriptions for easy maintenance
If you want reliable periodic updating of the antivirus program without extensive manual maintenance, you should purchase a program with an automatic subscription service. As an alternative, there are a number of good antivirus programs available for free.
We highly recommend that you use antivirus software to protect your PC, and on the internet you can find more info about antivirus software and suppliers.
