Should Microsoft defender run on my PC if I'm using AVG?

Arthur, Which Windows version are you actually using?.. Additionsal info… Windows Defender is an anti-malware component of Microsoft Windows. It was first released as a free antispyware program download for Windows XP, shipped with Windows Vista and Windows 7 and made into a full antivirus program replacing Microsoft Security Essentials as part of Windows 8 and later versions.
