I have no problems with Microsoft Security Essentials http://windows.microsoft.com/en-us/windows/security-essentials-download and it's free.
I did not see a specif mention of Windows 8 from the OP but in any case the functionality of Essentials is included already in Windows 8 http://answers.microsoft.com/en-us/...als-with/34b26e6f-12a0-4bc7-b160-f3b2ff70b910Says it doesn't support Windows 8
what's the difference between Microsoft security essentials and windows defender .
windows defender on my machine but have never switched it on
I have no knowledge of computers. I only use it for emails, searching and online banking. I have been told there is no need for me to instal anti virus and the risks only arise if i engage in "dodgy" sites. Is this sound advice?
