One of my PCs, which are all intalled with Windows 10 and using only Windows Defender as virus/malwares controls, continues to fail the latest Windows Defender's Definition Updates (i.e. being stuck at Definitions 1.239.1124.0) after prompting that "Because of an Internet or Network connectivity problem" even though I have activated the Windows Defender's "Definition Update", seeing the update being downloaded and installed. My Internet has NO PROBLEMS (because I could use my Browsers) at all! Besides I have tried this Windows Defender's Definition Updates in Administrator/Normal modes but still failing in that particular PC!
My other PCs which are having similar setups are O.K without the said problems. So may I ask how to resolve my problem, or do I need to re-installing Windows Defender??
Intel E4300 OC with 2GB RAMs,Speedtouch 585 Modem/Router and Windows10 !
