Command prompt window appears and disappears even when i am doing other stuff

[shiva20587]

Hello,
Command prompt window appears and disappears , I mean it runs itself,it opens up and closes as quickly as it popped up,it happens while I surf the internet or leave the computer idle for sometime. Is this a sign of some kind of malware?? I scan my computer regularly with microsoft essentials and later I switched to kaspersky, I never found any virus. I use windows 7 OS.

some schedule job running?

 

[pauls3743]

I've seen it while my computer install updates. My bet is that you have your computer set to automatically install updates, which is why you'll be seeing it at odd times.

No jobs were running, it happens even when the computer is idle.

if you do "shady" things on the internet, then you could of course be infected. keep Task Manager open to the Processes tab and monitor it to see what's popping in or out when the CP appears. If you can't figure it out, a fresh install of windows after deleting the partition it's on is the only way to be 100% clean.

also malwarebytes would pick up just about anything

Thank you guys for your suggestions, did not expect this quick response . I will try to install a fresh copy.

Hi,I have one more question ,
if some malware is behind this,why my anti virus programs did not work??
Is there any way of knowing that it is the work of malware, I mean I can re-install my OS but I just want to know if there is any other option?

Thanks.

Which anti-virus are you using? Update it and run a full scan. Then download malwarebytes and update it and run a full scan. Do this before you re-install windows to find out what is going on with your system. You might not even have to do a full install...

anti-virus is Just That - anti-VIRUS... Malware is completely different

This happens on my Win7 installation too never saw it until i rebuilt my pc with all new hardware and the same Win7 home premium retail.

I prefer the government spying answer. It's more fun than simple updates.

I don't see anything like it on my linnux box.

I have my PC configured so that all the drives come in and out of the bays in the front. I swap drives with different OS so my computer is leaving the same unique CPU identifier behind no matter the OS in play.

Hello,

Is this a sign of some kind of malware?? I scan my computer regularly with microsoft essentials and later I switched to kaspersky, I never found any virus. I use windows 7 OS.

This is perhaps now a very old problem which people may have solved.
However, it is any help, I found one possible solution - this is specific to a Windows 8.1 update.
If you take a screenshot of the flashing command prompt window at the moment it flashes, you get to know which file is running along with its location.
The file which I encountered is prcctr32.exe
It is located in c:\users\<username>\local\appdata\PRX\prcctr32.exe.
(This may be different for others, and even more so for Windows 7...may be).

Since this is a local app, I simply deleted the PRX folder and the flashing problem stopped. If the folder does not get fully deleted, and some .dll files remain, don't worry. Delete the rest and restart. Good chance that the folder 'PRX' will get deleted on its own when you restart.

A system analysis indicates that this is some kind of a trojan file, but I am not sure.
Microsoft is silent about it, so it may be a bug in the 8.1 update.

Hope this is helpful.
Please comment if there is a better solution.
Cheers!

I just did a screen capture and found out what mine was. It is the blackberry link peer manager which is part of the Blackberry 10 desktop software. I'm uninstalling the blackberry software now since I had just installed this for checking other people's phones since I have a android phone.

It just happened to me and it was too quick for me to hit print screen. One word I caught when it was loading though is "Roaming". Not sure if that helps since it shows up at random times.

No jobs were running, it happens even when the computer is idle.

No PC is ever completely idled. Just open the Task Manager and look at all that stuff sitting there just waiting to sprint into action.

Also check your scheduler.

Mine does the same thing... sometimes multiple times a day.

 

[LordSparxx]

I saw mine happen at exactly 12AM and i would think it was an update. Does the cmd section of windows have a log file. I am always thinking I am getting peered so I would like to know if things are going on. If something did update would i look in the log file config file services or some sort of bat file. please advise a logical progression of scouting procedures? thank you in advance.

I stupidly downloaded a torrent file and got a virus with it. I tried to remove everything, and thought I did. all that remains is this command prompt pop-up problem, it makes every game minimize when it does this. I've tried screen capturing, I've looked in task scheduler, I've tried searching for it, but it's still happening. I'm running windows 10, and I would really like it if someone could help me

I don't have an answer, but my computer is doing this too, and I'm desperate. It always minimizes whatever game we're playing. I'm so frustrated!

 

[Raul_McCai]

So I snagged a Screen shot of it doing it. It's the video player.
