Random split second pop up

Avast Free Antivirus / Premium Security
1

An annoying thing that’s been happening to me recently, to the point I made an account here. Not sure what’s causing it and google is no help because it brings up results for the regular kinds of “pop-ups”. I’ve been using Avast Free Anti-Virus for years now and recently I discovered this problem for around a couple of days now.

To describe it, it’s a small popup window of Avast that appears for a split second in the center of the screen before it immediately closes itself. Since it closes itself so quickly, I wasn’t able to determine what kind of message it is. It seems to occur every 2-4 hours and I’m not certain what triggers it to appear. Not even sure if the issue is Avast itself or something else provoking Avast.

Silent mode has no effect as either on or off has the popup occur. I tried updating avast, restarting my computer, using the repair app function in the settings, and repairing via uninstall. Those didn’t solve the issue. As of right now, I did an uninstall and reinstall so I’m gonna see if that fixes the issue or not.

Is anyone else also encountering this issue or just me?

I certainly haven’t experienced it, much less any idea why it would popup.
Have you made any changes to the default avast settings ?

Whilst it isn’t there for long, you could try to do a print screen PrtSc key. To help you find it quickly you could put a piece of HiViz tape on it.

Yes. This has been happening to me as well for the past couple of weeks. Google has been similarly useless for me. Hopefully someone can give some insight into what’s going on.

A Japanese user also reported the same issue.
He successfully took a screenshot of that window, although it shows nothing, just a blank with Avast title on it.

This started happening on my PC yesterday. It’s a window with the title “Avast”, but with nothing else written. It closes after about 1/8 of a second! I did get an Avast program update yesterday. I have Avast Premium Security.

I’m sorry for bump, but no answer from staff yet.

I have this issue too, random popup without any information on it, only blank window with Avast UI colors.
I’m using Avast Premium Security 20.6.2420 (build 20.6.5495.588), Windows10 Pro 64bit.

I don’t know what’s triggers it, I don’t change any Avast or Windows setting.

This happen randomly.

I am seeing a white “window”, about the same size as Avast UI window, flash on my screen after startup. It seems to occur before the Avast system tray icon appears. It happens so fast, I am unsure if it was an Avast window or not. This has been happening I think since 20.6 version update.

Getting something similar for a while too.
Current version is Premium Security 20.7.2425 (build 20.7.5568.595).

It seems to happen randomly regardless of how long my PC has been on and the window is a standard Avast one that appears in the middle of my main monitor before vanishing a split-second later.

  • OS…? (32/64 Bit…? - which SP/Build…?)
  • Other security related software installed…?

Been getting the same popup but I have only seen it doing this while watching YT. It hasn’t affected gaming or anything that I have seen but still annoying none the less.

Win10 Pro 64bit updated to 2004 AMD Ryzen 7 2700x
Avast Premium Security all up to date.

Hi guys, I forwarded it, let’s see…

12

Win10 Pro x64, fully up-to-date.
No other security software running.

Thanks again, Asyn, for the help. He pointed me to this post, which is an exact description of what I’m seeing.

Windows 10 Enterprise (64 bit), version 1803. OS Build 17134.1726
Avast premium security 20.7.2425 (build 20.7.5568.595)

not sure if it’s relevant, but I also run AirVPN at all times.

14

Doing the repair/reboot that was suggested by Asyn in another thread might have resolved this for me. I haven’t seen a pop-up so far where normally I would have expected a few.

15

At least on my side, doing a repair did not affect this.

Hello, sorry for magic windows, when induced, can you please:

  1. make a note of exact time, when it appeared
  2. copy all files from c:\ProgramData\AVAST Software\Avast\log\ pack them and sent it directly to me petr.blatny@avast.com
    thank you again

After seeing it quite a bit lately, I haven’t seen it for a couple days. Nothing on my computer has changed, though as it is just a sudden flash of a popup, it would be possible to miss.

Will be sending logs though when I do see it again.

Happening for a couple of weeks now since I last updated, very very annoying and hard to get work done with the constant popups, problem is identical to what was described by others in this thread.

I’ve sent logs to the email above, below is specs:

64bit Windows 10 Home 1909 - 18363.1082
Avast Premium 20.7.2425 (build 20.7.5568.596) / Malware Bytes Free 4.2.0

19

Same here, every time I log into my pc I get that split second blank Avast window popping up. Haven’t changed anything that would cause this, I do believe there was a database update I did this past week but that shouldn’t affect the program.

I’ve had this since the last update. It last a second or 2 when I’m using my PC.
When I’m away it pops up and stays until I use mouse/keyboard.
I use the free version.
It dawned on me today that I haven’t had any advertisements in the lower
right corner of my PC since the last update.
