I am a technician for a church. One of the pastors has 8 kids and always has malware. I have only been partially successful in cleaning an Arcade Yum infection. It will no longer run the ads but it still shows in the addons and removal is disabled in the addons menu for IE. I have run the following. Adwclean, Junkware removal tool, ComboFix ( this was before I had read that I was supposed to have someone tell me to do it) MalwareBytes, and Sophos. I also did a Kaspersky scan. I think it is hiding in the registry but I can't find anything that tells me which lines to delete in the registry, only stuff trying to get me to download Spyhunter which I believe has malware. I need to have this back by this Sunday. I have only partially resolved the problem. Any help would be greatly appreciated.
