i got the same issue here shortly after CTR went down....alot of sponsor links off of both these sites showed the same issues. Seems like any site linked offa these two sites were sporadically showing rogue scanner installer issues.
I run CTR and this shit is getting old. Gotta stay on top of updates... it ended up being another site's ad software being out of date which then led to a script crawling through other domains on the box.
