Disclaimer: Antivirus software can help protect the computer against viruses and other security threats. In most cases, you should not disable the antivirus software. If you do have to temporarily disable it to install other software, you should re-enable it
as soon as you're done. If you are connected to the Internet or a network during the time the antivirus software is disabled, your computer is vulnerable to attacks.
