OP,
download "Malwarebytes". Install it and run a scan.
Malwarebytes
It will quarantine what it finds,then let you kill it.
If you really want to "clean" your rig...
I suggest,
Downloading and installing,
1.
ESET Online Scanner
2.
RogueKiller
3.
SecurityCheck
4.
OTL
If all else fails,
go to Bleeping Computer dot com,
and download and install a program named, "ComboFix".
I did not post a link,because.....
It is
HIGHLY recommended though,before you run ComboFix,
to run a program called "
HiJackThis", and post your results on their Forum, as many there will guide you on your next steps.
You may have to change some Registry entries,
but their help will be very specific on what/how to do it.
You do know where "Registry" is and how to open it?
Also,
download "
CCleaner" and "
Spybot Search and Destroy".
Run CCleaner after each day,and SpyBot once a week.
