Qt Creator slowing down entire computer
-
That is really hard to say! Especially when windows doesn't really recognize which process causes the problem. The CPU was at 25% even after closing QT Creator. But the Task Manager didn't show a process which used more than 0%.
This behaviour appears like a driver problem. But I can't tell. -
OK, let's just blame it on the driver then;-)

No... I reinstalled my windows because i wanted to have Win8 anyways. (Sorry...)
But I'd try to uninstall every QT software from your system and then install 4.8.4 with creator 2.6.0. Please let me know if that worked if i get the problem again! ;)[quote author="Tobias Hunger" date="1355157395"]OK, let's just blame it on the driver then;-)[/quote]
I don't even know what drivers QT is using or not! ;) But these problem appears like a driver problem from my experience. (I know... It is just a brainstorming input from my side)
If i had the time to invest more time in QT than in my project, I would have questioned it a bit more. Sorry for that![Moderator's note: Removed duplicate post -- mlong]

OK!
I have the problem again!
This time I updated to QT5 rc2 with Creator 2.6.1
I also installed Visual Studio 2010. I compiled my project with the msvc2010 compiler and then with MinGW QT4.8.4
And YAHTZEE! Same behaviour like the last time. But this time I am using Windows8.I'm now going to reinstall the whole Qt stuff. If this wont change anything, I will uninstall my Visual Studio.
GRRRRRRRRRRThe only thing which is maybe special on my project is, that it is very huge meanwhile. It consists of 3 separate frameworks.
Does Qt Creator have something like an index database or something? Maybe it would help to delete it. -
OK Another thing:
Windows8 task manager shows more details of processes and services.
It shows up that the Kaspersky Service starts continuously filling my RAM!
It now has 1.5 GB reserved within 2 minutes! And the service runs at 28% CPU at all 4 cores!!!
Another Kaspersky service called "Dump Writer" fully loads my hard disk at 99%!!!!! WTF?But it only starts doing that when I compile anything with Qt Creator/MinGW
Sometimes when I compile anything, Kaspersky says: "qmake.exe/QTCreator has simmilar behaviour like root shell smth smth"
I don't get it. It worked for 3 weeks now and all of a sudden. BAM
What could be the problem?

Anti virus apps do all kind of strange things. I tend to just turn them off (or better: Ask them to ignore my development folders) whenever using windows. Even if they do not cause hassel they slow down compiling a lot and that already feels slow on windows, even without a AV looking over its sholders.

jack249: If possible just ask the AV to ignore your source/build directories. Don't turn of virus protection completely.
