I do have an issue that I am unsure of, its called 'keyserv.dll' and I can't find much description of it on the web.
This is its full title BHO: MSEvents Object - {B8B55274-0F9A-41E5-9067-A3539BD9E860} - C:\WINDOWS\Web\keysrv.dll
and I have found another reference to it with Winlogon:
Winlogon Notify: keysrv - C:\WINDOWS\Web\keysrv.dll
I get the occasion pop up redirecting to 42search.com (or something like that), but I'm not sure if its related.
I would be grateful if anyone can shed some light on this, thanks!!
