Slow PC After Pro Install? Disable Windows Defender
After installing System Mechanic Pro, some Windows 7 users may experience system slowdown due to an AV conflict easily resolved by disabling Windows Defender, Microsoft’s default virus/spyware protection. If you are already running a real-time AV solution from a third party, this step is most likely unnecessary. If you are not, you should disable Windows Defender. (You may have already received a message from System Mechanic indicating that System Shield real-time protection could not be enabled due to a conflict with Windows Defender.)
To turn off Windows Defender:
- Click the Windows Start button.
- Type “Windows Defender” in the dialog box and select it when it appears.
- When Windows Defender opens, select Options > Administrator.
- In the box on the right, uncheck “Use this Program.”
- Click Save and Exit.
You can also check Windows Defender’s status (i.e., whether it is enabled or not) by following these steps:
- Windows Start > Control Panel > System and Security > Action Center.
- Click on the down arrow on the right side of the Security section to fully expand it.
- Scroll to Virus protection and click Show me the antivirus programs on this computer. A window opens that displays the current status of each AV program installed on your computer.
- Repeat step 3, this time scrolling to Spyware and unwanted software protection, then clicking View installed antispyware programs.
