Dell Support Center has stopped working

I get this message constantly, it pops up like every 20-30 minutes and I can't open Dell Support Center.

Before, it was working okay, but I remember one time it wanted to do some scan on my computer and I was leaving and I just turned it off, maybe that's the cause?

How can I fix it?

EDIT Couldn't restore using System Restore

I don't know how to absolutely turn off antivirus, I use Avira and I deactivated AntiVir Guard, I don't know if it's enough

In my experience, Avira and AntiVir are horrible resource hogs. I actually still wonder if it's just a clever scare-ware operation – Earlz Aug 30 '11 at 18:50

Try uninstalling Dell Support Center again, delete anything else that may be in its original install directory (you have to look, but it is probably in c:\Program files), then run CCleaner's registry cleaner.

I also agree with running chkdsk /f (I would run it 2-3 times though).

Perhaps try Windows 7's in-built System Restore to go back to a point in time before the problem arose (i.e.: before you ran that 'scan').

System Restore can return your PC's system files and programs to a time when everything was working fine, potentially preventing hours of troubleshooting headaches. It won't affect your documents, pictures, or other data.

Open System Restore by clicking the Start button. In the search box, type System Restore, and then, in the list of results, click System Restore.

You could also probably just reinstall or uninstall the Dell Support Centre.

@Templar: I think you've got bigger problems than Dell's Support Centre then. :) Did you try reinstalling the Dell Support Centre? – Ƭᴇcʜιᴇ007 Jul 29 '11 at 20:42
yes I uninstalled it, but I can't install it again, because during instalation at the end I get same error Dell Support Center has stopped working – Templar Jul 29 '11 at 20:43
@Templar: Then that leads me back to "I think you've got bigger problems than Dell's Support Centre then". Start doing file-system, disk and RAM tests. If those all come up clean then install a fresh copy of Windows and see how it runs. Otherwise, we're just shooting in the dark. – Ƭᴇcʜιᴇ007 Jul 29 '11 at 20:46
also wanted to check disk for errors so went to my computer right click properties tools error-checking clicked check now and it says Windows can't check the disk while it's in use and asks me to schedule it, is it normal? because I think I remember it worked fine some time ago – Templar Jul 29 '11 at 21:00
