Experiencing issues with Dosearch attaching itself to both IE10 & Chrome (www.google.com is the homepage for both). Uninstalled DoSearch engine & DoSearch from Programs, Went into both IE10 & Chrome and cleaned up the searches / deleted Dosearch as search engines, and downloaded Malwarebytes Anti-Malware Free Ver 220.127.116.110 and executed it. Several entries / reg entries for Dosearch were found quarentined, & deleted (rebooted laptop). Tabs still exist with Dosearch in both IE10 & Chrome. Ran Malwarebytes Anti-Malware Free Ver 18.104.22.1680 again and it shows clean. Found, downloaded, and ran Spyhunter 4 and it shows several additional reminants, but they want $40 to buy their program & not sure that is the way to go.
Any suggestions would be greatly appreciated; Tha laptop is my son's new (3 months) HP TouchSmart laptop with Win 8.1 and he is a Freshman at college needing this cleaned up so he can use the laptop.
