Virus Protection

I'd Suggest You Better Skip The Idea of Using Those Security Suites. Better Use Some Free To Use Yet HIghly Rated For VIrus Protection Engines. Here's What I Suggest Top Three...


1. Avira AntiVir Personal Classic Edition
2. Avast! Home Edition
3. AVG Free

Avira Is Found To Trigger Less False Alarms Than Anyother AV (Even Paid Don't Have That Kind'a Accuracy), & Is Much Better Than some of The Paid Ones. Next Is Avast!, For It's Individual Scanner Protection & It's Unique VRDB (Virus Recovery Database) Feature.

If You're Looking For Firewall Protection Then Again, The Free Stuff Come To The Rescue.


1. ZoneAlarm Free
2. Comodo Firewall Pro.
3. PC Tools Firewall

We All Know How Good ZA Firewall Can Be..! Comodo Has Passed All The Leak Test That Can Be Serious For Your System Security. PC Tools Is Not New To The Scene Here, Still Has Very Good Firewall With Less Questions Asked, Recomended For NewBie.

@Try3

Thank you for your quick response. You have always been quick to respond.

This morning I updated the HP laptop to 21H2 through the normal Windows update. Do you still think I should do a repair install with 21H2 ISO?

I am posting three screenshots .













I am yet to try the suggestion made by @hdmi in his post #8

"See also options 2 and 3 in this tutorial:
Windows Defender not updating automatically in Windows 11/10"

I shall try it later tonight and report to hdmi. He must be waiting in the wings.

 

Nonstop alerts about virus protection

Hi,

Thank you for posting in Microsoft Community and being a part of Windows 10.

I understand your concern about accessing the operating system with the security notification on your device. We will help you with this issue.

Do let us know the following to assist you better with this issue:

• Have you installed any third-party anti-virus software on your device?
• Have you made any changes to the operating system prior to this issue?
• What is the complete error code/ error message of this issue?
• When exactly you get this error pop-up?

Try the below troubleshooting steps and check if it helps.

Step 1: If you have installed any third-party anti-virus software, I suggest you to disable it and check if it issue persists.

NOTE: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it to install other software,
you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.

If the issue still persists, I suggest you to uninstall the third-party anti-virus software.

Step 2: I suggest you to run Windows Defender on your device and check if it helps.

Windows Defender is malware protection that is included with and built into Windows 10. This software helps identify and remove viruses, spyware, and other malicious software. So, you do not need to install any third party antivirus applications.
