prosearchtip & prisearches/433-a.akamaihd.net malware
HELP! Suddenly prosearchtip.com has installed itself as my browser. I can get rid of it. i have used malwarebyte as suggested to no avail. I have gone to extension in Safari and none are listed. the listed home page is prisearches/433-a.akamaihd.net, but is greyed and I can't change it. What do I do at this point?
