ApplicationUpdater.exe was installed on my system when I installed YouTube Downloader Toolbar. After removing YouTube Downloader Toolbar through Control Panel, both YouTube Downloader Toolbar and Application Updater were removed successfully. Your results may vary.

Scheint zu Spigot (spyware) zu gehören, da sich hinter pdfforge bzw. Dealio eben Spigot verbirgt. Quelle siehe Link.

Some of the info above is inaccurate. The YTD Toolbar is not YouTube Downloader, it is from Spigot and is malware.
addware with keylogger and browser hijack capabilities

Best practices for resolving ApplicationUpdater issues

A clean and tidy computer is the key requirement for avoiding problems with ApplicationUpdater. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem.
