Hi Pondus,
What brings this into the category of to be detected by normal av is that junk and crap that cannot be normally uninstalled via the configuration uninstall method, should be flagged as malcode. These BHO search hijackers to score cyber-criminal fraudulent clicks are a pain in the proverbial behind for the average user and for cleansing a run of special tools like AdwareCleaner and junkware remover is required, else you cannot get the browser settings and altered registry right. BHO Browser Search Hijackers I consider to be malcode scam, despite what the developers may say. This is parasitic junk-ware and a form of stealing income from the decent ad-launchers.
