Windows Defender Scans 'Failing' After The Latest Windows 10 Update

Windows Defender Scans 'Failing' After The Latest Windows 10 Update

Recent antivirus tests have shown that Windows Defender, which comes pre-loaded on Windows 10, is now offering performance that's on par with the one of third-party software from the world's leading security vendors.

Windows Defender also sends out a notification error message to the Action Center when this happens.

Windows Defender, the anti-malware component of Windows 10, is skipping files during security scans for many users for no apparent reason.

It isn't made clear how many items were skipped, or indeed if any were skipped at all - there is the possibility that this is a false error, and the bug is simply the error message popping up (as opposed to files not being scanned).

It is hard to say exactly where the problems stems from. Some folks are even anxious that this error is a symptom of a virus itself.

Facebook and Instagram reduce video quality in Europe
Facebook and Instagram have made a decision to reduce video quality in Europe as part of the fight against coronavirus . Following Netflix's lead, YouTube announced today that all of its streams will be in standard definition by default.

Windows 10 often coming up with unknown problems is turning normal these days.

Users of Windows 7, Windows Server 2008, or Windows Server 2008 R2 are required to have an ESU license to receive future security updates fixing these issues (more information here).

A similar thing could be happening here. It seems Windows Defender version 4.18.2003 and newer introduced the bug when Microsoft was fixing other problems. A number of users have reported the issue to Microsoft, but it appears none have recieved confirmation that this issue is being looked into.

Apparently, Windows 10 devices are now affected by a similar problem these days. The problem disappeared until I ran Windows Updates, which installed KB4551762 and KB4537572 (which is NET Framework update, I believe). "I dont think Microsoft has dealt with this issue yet".

Microsoft has yet to acknowledge the problem, but it would be another example of the company's patches causing problems for unrelated services. There are complaints on Microsoft's support forums as well as Reddit dating back to the first half of this month, and it's leaving people unsure as to whether virus scans are performing correctly or not.
