Windows Defender seeing P3D as Malware!

Featured Replies

Hi everyone

 

What the hell is going on!!

 

I have just tried to re-install P3D and Windows 10 Defender flags up Prepar3D Set.exe as malware and removes it!! 

 

Anyone else seen this and why on earth hasn't Lockheed Martin sorted this with Microsoft??

AVG, Nortons etc etc having been detecting Prepar3D as malware for months and months!!!

Just add P3D directory in Windows Defender exceptions, easy fix.

I am sadly still getting the same problem .... Windows Defender informs me that the setup exe is malware and decides to uninstall it .....

 

I then decided to download just the setup exe individual component and then de-activate Defender in order to install Prepar3D which all went fine

 

About half an hour later Defender once again notified me that it was removing the 'so called' malware but as I had installed Prpear3D successfully I didn't worry about it .....

 

The one thing I have noticed is that there are now only three entries listed under 'Uninstall a program' in the 'Control Panel

 

The only three entries listed are:-

 

Install Client

Install Scenery

Install Content

 

The thing is .. Prepar3D is working fine so should I be unduly worried?

 

Cheers

Are you using smartscreen filters? I have this disabled as I know what I'm downloading :)

Hello!

I was faced with a similar problem, Avast saw all the files .exe as malware. After that, Avast missed Locky ransomware on my laptop. 

The solution I found here:http://myspybot.com/######-files-virus/ Now everything works well  :P

Hi, the problem is in Windows defender. I also encountered this. Here is another thread on this topic 


By the way, thanks for the links!

All flight sims meet the definition  of malware. They slow your PC's performance, are annoying, take control of your computer and drain your bank account, without you even noticing that the money is gone.
