This was a pain to remove. What I did was use CCleaner to get rid of the registry for ‘YAC’. However, it wouldn’t let me delete the program because it said I needed to be Administrator, which is BS. So, after i deleted the registry, I found the file was under the name ‘Elex-Tech’ in my Programs(x86). It wouldn’t let me delete the file, and it didn’t show up in Safe Mode. What worked: I cut the folder out of my Programs File, and pasted it to the Desktop. Then I could delete it! Then I ran my malware programs for safe measure. Hope this helps.
