Windows 7 pc opening up multiple processes

Just set up my new pc running Windows7 64-bit. After installing my Office 2003 CD, Excel started behaving oddly and throwing up error messages very frequently. Even more bizarrely, it’s opening up multiple instances of Excel all by itself. When I check in Task Manager, I see not only multiple instances of Excel, but other apps too. The screenshot illustrates it all nicely.

Go to Start|All Programs|Accessories|System Tools|System Restore and restore your system from a checkpoint created before you installed Office 2003. You won't lose data when you do that.
I would suggest finding out if this is really problem caused by the Office or something else went wrong, before restoring system.

I uninstalled Office 2003 and left it off for a bit and all was well. Then re-installed it and the problems returned. Are there any known compatibility issues with Office 2003 & Windows 7 64-bit?

I used to have what appears to be a similar problem with Outlook 2007 on Windows 7 32 Bit. This used to happen when closing Outlook then reopening. It creates an Outlook process but does not show the user interface (UI). Run Outlook again and it creates a new process with no UI showing. I used to terminate all running instances and reopen Outlook.

Problem was resolved after Upgrading to Outlook 2010.

If there is any possibility of malware, then you DO NOT want to run CCleaner!

Many variants of malware will move critical system and data files and folders into the Temp directories and CCleaner will permanently delete all of them.
Thankyou younghv I had forgotten that, putting it back onto new remember shelf.

Once the AV scans are done all is clean then check.
