I had DoSearches get into my system & decided to try Malwarebytes 14 day free trial - it seemed to work deleting 119 references to different malware, many for Dosearches, but after trying to pin Google to my task bar - the task bar will still open Dosearches for Home page instead of Google - I can open Google to correct page by right clicking the Google icon & click open new window - Don't understand why Dosearches even shows up after cleaning the malware, so am not so sure I will keep this Malware - may have to try others as there are many to choose from.
