Real Time Scan won't stay on. Do I have to reinstall?

Java 8 just updated to 91 and Real Time Scan won't stay on. I read the old discussions from several years ago and I hesitate to uninstall. Is there another more recent fix?

Moved this to Consumer > VirusScan.

Make sure your system clock is accurate and reboot, that may fix it.

Otherwise run the Virtual Technician to see if it finds and fixes anything.

Let me know how that goes.

I got the same problem with AntiVirus Plus 2016.
The real time scanner is still turning off and if im trying to do a quick or normal scan its making an error aswell.

Java is up to date aswell

Also tech support is only available from 9am till 6pm here in the netherlands?

If you are current and up to date with all of your Windows Updates/Add-ons/Extensions, to include Internet Explorer even should you choose to not use it. McAfee and other important programs do. To rule out any possible Malware, you can access some excellent complimentary Tools here;

Try running Malwarebytes (Free) as it functions differently than Anti-Virus applications. To keep it (Free) Do Not accept the (Free) trial , or activate the Paid/Pro Version. Should the scan come up clean, and MVT did not detect any issues.

Short of doing a Clean Uninstall/Reinstall, I would contact Technical Support as soon as possible.

Please let us know your results....

This can happen for a number of reasons, use of registry cleaners, or even System Restore can sometimes mess it up. 

If the above Virtual Technician doesn't help and you don't want to be bothered by a Technical Support person the only real solution is to uninstall everything via Control Panel > Programs and Features.  

Run the MCPR cleanup tool, reboot and reinstall.

A hint to save a lot of time ....go to your online account page before doing the above and download to your desktop the installer.

Then you can install right after that reboot without having to go online with only Windows Firewall protecting you.

Hello Ex_Brit,

What are registry cleaners?
I haven't done any system restores in monthes.
Since today I got these problems, I have tried to reinstall Mcafee today. I had tech support yesterday and today aswell since, I got problems with installing aswell. (Installation is incomplete) After a lot of tries Mcafee finally installed on the computer.

Hello catdaddy,

Does Malwarebytes also delete the corrupt files if the scan wont become clean?

All windows, add-ones and extensions are up to date, since the Tech supporter helped me yesterday and today with installing Mcafee again because I got installation problems with it aswell (Installation Incomplete error).
After couple of tries the installation went good, but now this is happening.

Re: Real Time Scan won't stay on. Do I have to reinstall?

Check that your internet connection is always available and your system clock is accurate, also if by any chanmce you are running Windows 10, turn off Fast Startup whcih is a misnomer anyway and makes little difference.

As that prevents a clean restart which some software updates require.

Here's a "Tute" on that: Windows 10 Forums

If other systems, do a clean shut down and restart.
