(SOLVED WITH 6.0.1044)_1035/B:loop scan on file avastui.exe and hangs system.

Hi all.
After I install 6.0.1035 on the 6.0.1000, the my test system (other pc):

  1. avservice.exe action a infinite loop scan of the avastUI.exe;
  2. the AvastSvc use most cpu;
  3. after, the system hang.
    Is impossible use the osrbang.exe or a other program for create the dump of memory.
    I reinstalled the 6.0.1000.
    And now?

Obviously some program keeps opening the AvastUi.exe file. Someone reported here that e.g. PC Tools firewall can be doing this. Do you have PC Tools firewall installed? (or any other 3rd party firewall)?

No, absolutely nothing.
I have no idea how to help you.

Hi All.
Any suggestions?

Yeah, get something like Process Monitor and find out what’s opening AvastUI.exe all the time.

It seems from your signature and post that you are now using Avast Pro 6.0.1035

I have never used Avast Pro so maybe the directory path for AvastUI.exe shown in your picture is different than it is for AIS 6.0.1035

Here is the directory path for AvastUI.exe on my computer. Program Files\AVAST Software\Avast\AvastUI.exe

I am not sure why you would have the directory path for the AvastUI.exe in 6.0.1035 shown in your picture.

Does someone know if the directory path shown in the picture is correct?

I would also do search of your HDD to see if you have more than one copy of AvastUI.exe

ok, here’s a good solution:
download unlocker v1.9.0
go to the file location , in your case avastui.exe (as mentioned in the reply above me)
press right click > unlocker
and you will see which file executes avastui.exe + you will be able to unlock the file whenever you need to or any other file you want to unlock!
done :slight_smile:

It depends on clean install of v6 vs. upgrade from v5. Has nothing to do with the issue at hand otherwise.

I suggest to delete remains of old Avast! 5 version. Or try to repair avast!
isn’t this part on your computer? Program files\Alwil software… ?

Use latest version of avast! Uninstall Utility.

  1. why you sent it to me ? :stuck_out_tongue:
  2. isn’t that utility deleting Avast! 6 as well?

Why are you even suggesting uninstalling?! ??? The path is normal after upgrade from v5 to v6.

Just trying to help, quoting your answer. Nothing more, nothing less…

Yeah, you need to choose the avast version (from 4 to 6).
You’ll need to reinstall version 6 after that, most probably (not tested personally).

  1. It is a multi version uninstaller, but you select which version to uninstall, it doesn’t uninstall versions at once.

As doktornotor mentions, an update from avast 5 to avast 6 rather than a clean install will retain some of the old data/registry locations as it is too big a job trying to change all the registry entries. A clean install of avast 6 is in c:\Program Files\AVAST Software\Avast\ otherwise it would be c:\Program Files\Alwil Software\Avast5\

Never tried this tool…
Yeah avast! 6 dir is in AVAST software, but avast! 4/5 in ALWIL software

The point is that @GaAs should do an uninstall using the Avast5 uninstaller and a clean install of 6.0.1035

Also your comment doesn’t address the possibility of having two AvastUI.exe files which might be causing the problem.

Pardon me but I really don’t see how this removal tool/uninstall/reinstall frenzy is going to fix some third-party crap opening AvastUI.exe all the time. How about finally finding the offending application per suggestions above instead? Even if you had 1000 AvastUI.exe copies all over your system, there’s no reason why something should constantly attempt to open them.

Okay if you say so. ::slight_smile:

Okay so this is what I see.

  1. Based upon the thread title the Avast is in a scanning loop that hangs the system.
  2. Based upon the picture supplied it appears that File System Shield is scanning AvastUI.exe.
  3. Based upon the picture supplied it appears that the AvastUI.exe file being scanned is in the Avast 5.x directory path.

So it seemed to me that by doing an uninstall of Avast 5 and maybe even Avast 6 you will be removing the copy of the AvastUI.exe file in the old Avast 5.x directory path that the File System Shield says it is scanning.

Therefore if you remove the file that is being scanned you will remove the loop scan problem.

That is how I see it.

Probably missed something here. What did I miss? Thanks. :slight_smile:

Yeah, you are missing the fact that the AvastUI.exe path is normal and expected for anyone who upgraded from v5 to v6.
