New laptop running Windows 7 Professional. I have downloaded and installed Avast free antivirus. Looking at the setting laptop is also running Windows Defender. Should I turn off Defender and if so how.
Defender is an anti spyware programme but not a very good anti virus one. I just remembered how I turned mine off. Open Action Centre (little pennant in taskbar) .Click on Security. In section on "Spyware and Unwanted Programmes" , click on "View installed antispyware programmes" . You will see Avast and Defender, on. Right click on Defender. select Turn off.
PS I would also have Malawarebytes and Superantispyware - free but you need to scan and update manually. I use the pro version of Malawarebytes (Jock 1e gave me a link to the lifetime subscription) as I found a few months ago that Avast in the continuous web surveillance mode `seemed to interfere with iCloud
When referring to Defender you have to make sure whether you are talking about the W8 or W7 version. The W7 version is anti-malware only and isn't that good. The W8 versions includes anti-virus and replaces MSE but also is not very good.
