So I go into task mgr and delete them and they just keep coming back. I play Second Life so they are mostly under the viewer Singularity but I've seen them further down in Task Mgr also under Background Processes.

One thing I forgot to say is dullahan_host multiplies like crazy. I did a malwarebytes scan and it found something and I thought that fixed it but the next day it was doing it again.

Any ideas appreciated.
thanks, Cheryl

Sometimes the dullahan_host.exe does not shut down when you exit the viewer, especially if you are still using Windows 7.
Having these ghosted Dullahan processes running will absolutely affect the viewers performance.
When logged out of all SL viewers, just end the Dullahan_host processes via task manager & check in the future that none are left running after logging out of the viewer.

otherwise
Try running this: https://www.bitdefender.com.au/solutions/free.html

Thanks, I ran BitDefender and Avast before that...all comes up clean. There are 15 instances of dullahan_host when I start Singularity, but only 2 are showing CPU usage...1% and .4%. I moved my Avatar and now there are 45 dullann-host files in taskmgr. I might go ahead and delete the program and reinstall it. But appreciate your help. :)
