Disable antivirus software
Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your 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 your antivirus software is disabled, your computer is vulnerable to attacks.
Windows does not come with antivirus software, but can often detect and monitor antivirus software that you or your computer manufacturer installs. The status of your antivirus software is typically displayed in Windows Security Center.
Open Security Center by clicking the Start button , clicking Control Panel, clicking Security, and then clicking Security Center.
Click Malware protection.
If Windows can detect your antivirus software, it will be listed under Virus protection.
If the software is on, check the Help that came with the software for information on disabling it.
Windows does not detect all antivirus software, and some antivirus software doesn't report its status to Windows. If your antivirus software is not displayed in Windows Security Center and you're not sure how to find it, try any of the following:
Look for the antivirus software in the list of programs on the Start menu.
Type the name of the software or the publisher in the Search box on the Start menu.
Look for the icon in the notification area of the taskbar.
