Avast creates problems when taking screenshots

Avast Free Antivirus / Premium Security
1

I noticed that in games I cannot take screenshots when avast is active. Most of the time it takes screenshot of a wrong picture (looks like a blank loading screen of the game) or from desktop after I alt+tab a few seconds later. Disabling avast protection temporarily solves the problem.

I use windows+print or lightshot for screenshots.

Currently I am trying to take screenshots in Fortnite from Epic Games.

Taking Screenshots via Steam’s own feature works, but it is unusually slow (laggy).

By suspicion is that avast is scanning each file before it is saved correctly.

The prnt-scrn button on the keyboard is working fine for me.
The problem with those tools is that they don’t grab the screen directly from the GPU.
Let us know if the button is working for you or not.

Hi ptrckbrg,
does re-enabling shields bring the issue back immediately? Could you pinpoint the problem on a one specific shield by turning them off one-by-one? We never heard about this problem before.
Thanks.

The easiest way to turn off individual shields is via Settings,

Hi, thanks for all the help and excuse my late reply!

I just tested it with different settings and it looks like it is a combination of File Shield and Mail Shield. Disabling only one still causes problems.
When both are inactive, I am able to create screenshots with no problems.

I tested taking screenshots with an external tool (lightshot) with windows feature (win+print) and with normal printscr (clipboard).

Again, It always creates a file, but the problematic screenshots are either wrong (generic game screen/default background) or the screen after I alt+tabed back to destop.

Edit: I just did a test with the lightshot app closed, still problems with avast active. Testing Fortnite the Game atm.

Maybe you should give Greenshot a try: http://getgreenshot.org/

Tested more games. Fortnite, Stellaris and Pyre have problems. Sometimes no screenshots are created at all. Other games work without problems. (Slime Rancher, Rimworld, Lotro)

Pyre does not allow screenshots with or without avast enabled.

It is really hard to reproduce some errors, so I am not entirely sure if it has something to do with avast at all. So weird…

I just tried multiple screenshots with avast on and off in stellaris. No success. but then, there it is, an ingame screen.

I give up…

Have you considered that some games may disable that function ???
