bad case of adware?

[peticsu]

When I start my computer I have two to four iexplore.exe's running under SYSTEM, I can hear the clicks, and sometimes theres a popup but when I try to end the process, they instantly pop back up, then minutes later all the sound on my computer goes completely out. Spybot and malwarebytes didnt find anything...can anyone recommend anything?

Thank you

Hi, and Welcome to Malwarebytes!

Please read the following so that you can begin the cleaning process:

As we don't deal with malware removal in the General Malwarebytes' Anti-Malware Forum, you need to start a topic in the Malware Removal forum so a qualified helper can help you fix any malware related problems/infections you may have.

• Please read and follow the directions here, skipping any steps you are unable to complete. Then post a NEW topic here.
  
• After posting your new post, make sure under options, you select Track this topic and choose Immediate Email Notification, so that you're alerted when someone has replied to your post.
  
• One of the expert helpers there will give you one-on-one assistance when one becomes available.
  
• Please refrain from making any further changes to your computer (Install/Uninstall programs, use special fix tools, delete files, edit the registry, etc...) unless advised by a malware removal helper. Doing so can result in system changes which may hinder the attempts by a helper to clean your machine.
  

NOTE: Please DO NOT post back to (bump) your topic within the first 48 hours.

Replying to your own posts changes the post count and helpers are looking for topics with zero replies. If you reply to your own post helpers may think that you're already being helped and thus overlook your post.

• • If there is no reply from any experts after 48 hours, you can reply to the topic, asking for help again.
    Or
    
  • You may send a Private Message to a Moderator asking for assistance.
    

Alternatively, as a paying customer, you can contact the help desk at support@malwarebytes.org or here.

Please be patient, someone will assist you as soon as it is possible.

PS: Please use the "ADDREPLY" button instead of other ones when you start replying.
