I've been trying for the past few days to resolve my popup issues. I located your site by doing a google for "DiskCleaner" which was one of my symptoms. I ran Hijackthis a few times along with your other recommendations, I tried to repair things myself but I’m at my wits end. Thank you for the help in advance. I will attach the log files you recommend and will do a follow-up post with the remaining logs. Thank you for all your help!
