Sorry, somehow I posted this in the wrong place before. I hope this is the right spot.
I get a certificate error and a warning that a server might be trying to trick me when I try to log on to yahoo mail or my isp mail.
I ran Hitman pro and it found what it called a hijacker. It cleaned the hijacker and the messages stopped. Then they started again later on that same day.. I ran hitman pro again and it did not find anything. Malware bytes, Kaspersky, trend micro also did not find it. I guess the "hijacker" adapted. Rogue Killer found some suspicious stuff, but I deleted it and it did not stop the problem.
is there anything else I can try? Thank you so much for your assistance.
