"Installer" Process taking 2 GB working-memory

Question

  Hello, my Problem is the following:
- My iMac gets so slow, that nothing works anymore - I can barely restart, that takes minimum 1 Minute
- I found out, that a process named "Installer" is appearing regular out of nowhere and is taking almost 2GB working memory, then I have only about 10MB left, which is ofc too less (I got 4GB working memory in total)
-When I kill the process, everything runs normal again, and my working memory is back.
Has somebody an idea, where that process may come from, and how i can stop it?
I don't want to kill the process every day again and again, because it appears about every 2 hours.
I already went to Apple Menu > System Preferences > Users & Groups > Current User > Login Items  and took all hook out - It's still not fixed.
I hope for help,
Greetings CFB
