I installed the MCAFEE SOFTWARE that came with my broadband set-up the other day and uninstalled the NORTON that came with the computer and ever since I've been getting the following error message at start-up:

title: MemCheck.exe - Common Language Runtime Debuggung Services
body: APPLICATION has generated an exception that could not be handled.
Process id=0x9a8 (2472), Thread id=0x99c (2469)
Click OK to terminate application
Click CANCEL to debug application

I have an Acer laptop and believe that this is a problem related to them, has anyone elese come across this before and know how to fix it?
That file BELONGS to Ontrack's Fix-it Utilities Suite. It's a third-party anti-virus program that often comes with Acer computers. Personally, I think you're better off with having AVG instead of Fix-it or McAfee. AVG is free and it works a lot better. If you don't need Ontrack's Fix-it Utilities Suite, feel free to remove it with Add/Remove Programs. This should fix the problem. Also, check THIS PAGE and make sure Norton is properly removed. I would also remove McAfee and replace it with AVG or another free alternative, but that's up to you.
