Arrived with download of IE7PRO. Deleted it through a DOS boot from floppy. Massive resource hog.

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.

Zuh

i had installed a player called Veoh and when i unistalled it my firewall informed me that Au_.exe is trying to access "http://www.veoh.com..."

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.

Appeared in temp folder when I uninstalled WinPcap(Also not installed by me)

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.

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.

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).

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.

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.

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.
