E-mail attachments, programs downloaded from the Internet and web pages you visit can infect your computer with a virus.
You can protect your computer by installing antivirus software that scans your computer for viruses and malware.
Automatic updates for easy maintenance
Antivirus software can only protect you from viruses that were known before the last update. New viruses proliferate. To avoid infection, you should configure your program to update itself automatically or perform a manual update at least once a week.
