I have a Dell XPS 8300 with Windows 7. My computer was infected with several trojans yesterday. Each time I scanned with different software, I would find more trojans. My computer is running fine so I hope it's clean now, but will continue to monitor.
However, whenever I boot up, I now get a dialog box that says:
ATI Catalyst Control Centre: Host application has stopped working.
I went into my Device Manager, and nothing seems amiss. Why am I getting this alert, and what can I do to repair the problem?
You are most welcome. I'm glad we could answer your question.

Have you tried to uninstall and reinstall the Catalyst Control Center application.? http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_programs/catalyst-control-centre-host-application-has/300ad69b-1210-4bd7-97c9-12986a2241a8
Thank you so much - that worked!
