suddenly appeared when removing a program called Regiry Helper

It really depends on the actual file, 99% are probably harmless, but its possible to call a file by any name so its impossible to say if its safe or not

part of installer/uninstaller process which was discovered while uninstalling pre-installed gateway games off a gateway laptop. could be used to install/uninstall legit/safe software or malware in the event a software author used it as its installer. this task should only show up in taskman while installing/uninstalling applications. if seen running all the time then it is most likely an imposter/malware binary sucking up your system resources at the very least.

I think it appeared while trying to uninstall IMVU, a virtual chat software. At least, I've never seen it before doing this..

Uninstalled kdiff3 and au_.exe tried to install itself -- it was blocked by my ZoneAlrm.

SpyWare, Many Google Searches bring about Spyware results and many hits in 'Trojan, Adware,' etc... DELETE IF SPOTTED.
  RomanBell   (further information)
Appeared in temp folder when I uninstalled WinPcap(Also not installed by me)
  Gemin  
Threadfire detection of AU_.EXE opun uninstall of Comodo Geekbuddy. Believe it to be harmless in this case..
   
I just got a warning from my Firewall preventing Au_.exe from using a Windows messaging system component. This happened while uninstalling Widi 3.2 Trial. However you look at it , Au_exe is used to send/ collect information to a server. The people behind the server may be legitimate. Even if they are its still a breach of our privacy, and is therefore a sort of Trojan. The last Au_exe I had connected to a Russian server and tried to download more viri. This penetrated both firewall and virus scanner, my router firewall and other security software. My advice is kill it, block it, delete it.

Yahoo toolbar uninstall program, runs to instal and uninstall the program, when i uninstalled yahoo this file ran in the temp folder and then once yahoo was removed the file was automatically deleted.

I believe it came in with update to flsh player. Has captured my home page and blocked email access. Definitely a malware program. Now shows up in task manager using 98% of resources
  peter yule   (further information)

  Bruce  
It's actually supposed to be part of the MiniyLyrics program

Au_.exe appeared when I tried to uninstall Spotify. Avast suggested I open it in a Sandbox, so did, then it popped up with another warning for Bu_.exe - in the end I uninstalled without using sandbox feature.

  Ric  
This is a nasty little thing that came about when I installed iLiVid and Real Player when I couldn't get the programming I wanted from Graboid (REALLY stupid move).

  dakisan  
my anti virus has detected as low level risk and i deleted with norton anti virus
  A.aquilani  
won't let you uninstall yahoo toolbar
   
For me, Process Manager lists it's parent as "Uninstall Dragon Age.exe", which makes sense because that's the first I've seen it - uninstalling Dragon Age.
   
Found when downloading epicbot, it connects to a russian server as I used wireshark.
  EskiBoy  
AU_.exe appeared as ahigh-level threat (AVG) when uninstalling a spyware toolbar. Removal significantly improved system performance. My guess based on incidental reports: malware that ties itself to other software and triggers on uninstallation.
  SethC  
Antivir alerted after updating TeamViever and Teamspeak. Killed 5 process and 51 files. Could be used by TeamViever to uninstall the outdated client.
  Gnseblmchen  
My Kerio firewall alerted an outgoing TCP/IP request as soon as I removed Searchya toolbar for IE (from control panel add/remove) . Searchya toolbar was nagging / behaved like a mal-ware.
  Pongapundit  
Au_.exe is used by Yahoo toolbar, apparently to make it persistent (hard to completely uninstall)
  dannyr174  
Showed up during uninstallation of BT broadband helper
  Alan  
All of my Antivirus/malware/spyware programs point to this as the central cause of many issues on my computer: Freezes, denied access to files, unwriteable temp folder(which results in installation of programs being impossible. I don't know how to remove it for the life of me but if you can then get rid of the damned thing!
  Mike  
I have it on multiple computers. Seems it has to do with uninstallers, but it can also be malware... or maybe you guys are talking about Au.exe, which has a difference.
  ZZZZZ  
it stands for AUTO-UNINSTALLATION..(or only a part of its scripting) only appeared while uninstalling DAEMON Tools Pro (^^although in this case it did not ask for net access)
  SliXuZ  
Prevents Nik add-ins for Photoshop or Lightroom from running. It is a nuisance but does not afflict my 32 bit system. Only my 64 bit HP laptop.
