Solved Iexplore.exe virus

[Demon13]

My little brother's computer seems to be infected by a virus. He noticed that the sound would drop to 0 (wave volume). He also noticed sounds like the ones when you navigate through folders. We opened up the task manager then looked at the processes. We found that there were a few iexplore.exe even though it is not open. We tried ending them to see if it worked, but they just opened themselves a few seconds later. We looked for some solutions but couldn't find anything. I stumbled upon this site, and started to follow the 8 Step guide hoping it might help.

It seems as if this virus has been out for some time, and outbreaks of new strains appear every so often.

Sorry if something is missing or is wrong, please let me know if this is the case.

Hope someone can help, Demon13

Excellent
Restart computer and check for iexplore.exe and wave issues.

 

[Demon13]

I do believe you sir are magical. I checked for iexplore.exe in the task manager processes and it wasn't there. The sound issue hasn't come up either. I will definitely make sure to post back later today (it is 1:27AM here) with further results. Hopefully it is fully removed.

Thanks so much for the help!

I'm glad to hear good news
I'm about to go to bed too, but we'll have to run more checks.
Whenever you have a chance....

3. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

   NOTE1. If Combofix asks you to install Recovery Console, please allow it.
   NOTE 2. If Combofix asks you to update the program, always do so.
   • Close any open browsers.
   • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
   • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
   • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.
4. Double click on combofix.exe & follow the prompts.
5. When finished, it will produce a report for you.

**Note: Do not mouseclick combofix's window while it's running. That may cause it to stall**

Make sure, you re-enable your security programs, when you're done with Combofix.
