Since we don't need Internet Explorer the problem is easy to solve.
I know this issue has been discussed in former discussions, and I read most of them. But nothing I read appears to address my specific problem.
One post said to look for an MDM.exe file in my Task Manager, which I did. It was not there. I also disabled the "scripting" options in Windows Explorer's Advanced tab. The CPU usage didn't seem to improve. I also looked for the svchost.exe file in C:\Program Files\svchost.exe. I was told that no such file existed.
While I do see as many as 5 svchost.exe processes running in the Task Manager, most do not appear to be using any CPU power.
Nonetheless, each time I begin browsing, the Task Manager screen in my Taskbar is fully green. Then when I click on the Processes tab in Task Manger, I see that iexpore.exe and pctsSvc.exe (a Spyware Doctor programs I am running) are both consuming very high CPU power and memory.
I sent a system scan file to PCTools to see why this pctsSvc.exe process is using so much CPU power. But no one -- other than rouge spyware,malware vendors wanting to sell me their spyware software--no one has offered a satisfactory resolution to the iexplorer.exe issue.
My OS is Windows XP Pro, and my processor is an old AMD Athlon 1.0-Gig. and 2.0 Gig of DDR.
