McAfee antivirus software, in addition to updating the operation interface, also integrates the company's WebScanX function, adding many new features! In addition to helping you detect and remove viruses, it also has a VShield automatic monitoring system that resides in the System Tray. It automatically detects the safety of files when you open them from disks, networks, or email attachments. If a file contains a virus, it will immediately warn you and take appropriate action. It also supports quick menu functions with the right mouse button, and you can use a password to lock your personal settings so others cannot tamper with them. Note: Version 4.0.1 uses Dr. Solomon’s virus engine and adds the ability to detect malicious Java Applets and ActiveX programs, with a completely refreshed interface. Remember, virus definitions need to be updated regularly!
