iexplore.exe hogs 97% of CPU power and memory

by Mainman407 / August 25, 2011 6:09 AM PDT

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.

Since we don't need Internet Explorer the problem is easy to solve.

What exactly do you mean by: Since we don't need Internet Explore the problem is easy to solve? Are you suggesting that I switch to an alternate browser explorer such as Foxfire, Mozilla, or what?

You guessed the answer.

Try that. The issues with IE are now legend. You can use other browsers till more clues are found to why IE is whacked out.

ALWAYS the frst thing to test

is IE's Add-ons.

Disable all the add-ons and test CPU Usage. You can do that with IE's own 'no add-on' option in Start > All programs > Accessories > System Tools > "Internet Explorer (No Add-ons)".

If that solves the cpu usage problem then you know where to look.

Add-ons disabled

I disabled the IE add-on option but the problem was not resolved. I'll try again using the proceedure you discribed.
Would you happen to know why an Active X box appears at the top of the screen each time I access a webpage? Why would I need to add Active X for each website?

In reply to: Add-ons disabled

ActiveX is Microsoft's version of browser component software that allows web sites to be enhanced; for example, playing videos within a browser page instead of having to open a media player already installed on your system.

What version IE is this, because I thought the latest version of IE available for XP, IE8, did away with ActiveX at last. If you are seeing ActiveX in the "IE, (No Add-ons)" version, then that is because all ActiveX has been disabled.

If you are seeing ActiveX messages in the normal IE, then that means your security settings are too high, and are not letting web sites download and install their own ActiveX browser software

Other browsers do not use ActiveX as it is proprietary Microsoft software. It is generally recognised as a vulnerability and that is why Microsoft has done away with it in later versions of IE.

If that iexplore.exe is still using 100% CPU even with all add-ons disabled then that is strange and it points to something other than IE.

Time, I think, to take up Bob's suggestion of using another browser, and also I would suggest you scan for malware. Not just viruses that your anti-virus scanner should be protecting against, but other malware that it doesn't find. I would use the free versions of Malwarebytes Anti-malware and SUPERAntiSpyware.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
