Malware installing addons on my browser

Well I cannot be sure ,but there is a malware that keeps installing add-ons.It looks like it does it trough cmd ,because it opens twice for like a half of sec and then closes.How can I track it?

I recommend the standard "Big Three" response...

AdwCleaner
JRT
MBAM (free)

Let each clean whatever they find...

Thanks ,I used MBAM and it did the job,but is there a way to do all that manually?
