How to uninstall Crystalys media - cm.dll creates popup windows
2 comments. Current rating: (1 votes). Leave comments and/ or rate it.
I found my computer to have slowed down real bad, and no surprise, popups had come back.
I looked in folder \Program Files and sure enough found a new folder named Crystalys media there. (The trick is to look for new folders by sorting by time.)
You can see the contents of that folder in the grey box below.
At first I tried to delete the folder c:\program files\Crystalys media directly.
I found it to be here:
It deleted all files in there except file cm.dll which was in use.
Rename the file from cm.dll to junk.dll - we will delete it at a later time.
It turns out that this cm.dll is a BHO (Browser Helper Object) registered with Internet Explorer. I started the registry editor (start button, click on "Run", type "Regedit" and hit enter) and did a search for cm.dll.
and deleted the whole branch. Before you delete, make sure you really found cm.dll, and not some other file ending in cm.dll e.g. Outlook's "outlcm.dll". Hit F3 to repeat the search - there will be at least 3 more places referencing file C:\Program Files\Crystalys media\CM.DLL
You should also search for the rather unique folder name Crystalys instead.
This will find one more location in the registry - to keep it clean, delete that branch also.
Just for the fun of it, you could also run the 'uninstall' through the control panel- this little pest does have an entry there but I did not even try to find out how effective this part is.
Then restart your system and delete the folder afterwards.

I am getting an error at start up that says it can not find crystalys media cm.dll.
Is this is good thing? and if so, how do I stop that error window that now opens when I start my computer?
