I running Windows 7 Home Premium Service Pack 1 on a 64 bit OS. I have had Malwarebytes Premium running for a year with daily scans. Two instances of iexplorer have started running and chewing up the CPU cycles. I am unable to kill the processes as the pop back up. Does anyone know where I could have picked up this problem and how to get rid of it. Thank you for any time and consideration you can spare.

Hello PCos and welcome to Malwarebytes,

Continue with the following:

If you do not have Malwarebytes installed do the following:

Download Malwarebytes version 3 from the following link:


Double click on the installer and follow the prompts. If necessary select the Blue Help tab for video instructions....

When the install completes or Malwarebytes is already installed do the following:

Open Malwarebytes, select > "settings" > "protection tab"

Scroll down to "Scan Options" ensure Scan for Rootkits and Scan within Archives are both on....

Go back to "DashBoard" select the Blue "Scan Now" tab......

When the scan completes deal with any found entries...

To get the log from Malwarebytes do the following:
  • Click on the Report tab > from main interface.
  • Double click on the Scan log which shows the Date and time of the scan just performed.
  • Click Export > From export you have two options:

    Copy to Clipboard - if seleted right click to your reply and select "Paste" log will be pasted to your reply
    Text file (*.txt) - if selected you will have to name the file and save to a place of choice, recommend "Desktop" then attach to reply

  • Please use "Copy to Clipboard, then Right click to your reply > select "Paste" that will copy the log to your reply…


Download Farbar Recovery Scan Tool and save it to your desktop.

Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.html

Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way...

Be aware FRST must be run from an account with Administrator status...
  • Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.)
  • Make sure Addition.txt is checkmarked under "Optional scans"

  • Press Scan button to run the tool....
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  • The tool will also make a log named (Addition.txt) Please attach that log to your reply.

Let me see those logs in your reply...

Thank you,

Thanks for those logs, I do not see any obvious malware or infection. With regard to "iexplore" those are related to Internet Explorer, when you open IE there will be two iexplore.exe running in Taskmanager, after that when you open another tab there will be another entry of iexplore, and so on with each extra tab. If one of the links opened in a new tab crashes, only that tab would crash and not Internet Explorer...

Internet Explorer is your default Browser, can you close out Internet Explorer and use Firefox. Then open Taskmanager, there should be no entries for iexplore.exe.

Close Firefox, open Internet explorer with only one tab. Check Taskmanager there should be two iexplorer.exe. Open another tab, another iexplore should appear in Taskmanager...

Kevin, the iexplorer processes did indeed go away when I closed Internet Explorer. I closed Firefox and reopened IE and things act as you said. I'm curious as to why everything settled down and my system seems to running efficiently again. Any idea why those process were taking so much CPU?

A search of the internet indicates others are having a similar problem. Hopefully this helps them also if they find it. Expect a donation.

Hello PCos,

I cannot give a reason why your system was using excess CPU,  there was no obvious malware or infection in your logs. Run the following to remove FRST and its created folders...

Right click on FRST here: C:\Users\Pat\DesktopFRST64.exe and rename to uninstall.exe when complete right click on uninstall.exe and select "Run as Administrator"

If you do not see the .exe appended that is because file extensions are hidden, in that case just rename FRST64 to uninstall

That action will remove FRST and all created files and folders...
