Vapsup - How to remove

Vapsup is flagged as adware and has might come in many different varieties.  This parasite will display large amounts of pop-up advertisements, which are likely to make you go on a rampage. Vapsup is also able to modify online search results, thus making it a perfect alibi if your wife asks about the multiple porn searches you performed last night (in most other cases, though, it’s really annoying). Vapsup monitors your online activity and sends it’s observations to third-party servers for analysis.

Albeit highly unlikely, Vapsup may steal sensitive personal information, which can lead to identity theft and so on. Mostly, however, Vapsup will simply annoy you by slowing down your system, your internet connection and flooding you with pop-ups. Vapsup’s presence is dangerous and vexing, which is why you should remove it upon detection.

Some versions of Vapsup might disable task manager to make stopping its processes difficult. To enable task manager again, before removing Vapsup, modify registry and
set "DisableTaskMgr" to 0  under [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System]
