All comments about KHost.exe:
rate3 I think it has to do with Download.com and the Secure Download feature  See also: Link   Matt
rate0 Appears to be benign - but it is still on my suspect list  See also: Link   Ande Anderson
rate1 I believe it to be a GameSpot DLX Secure Delivery file   Mc El Dillorin
rate3 I tried to get GameSpot dlx Secure Delivery, used task manager to shut it down, message said khost.exe is not responding. I went into end processes and shut it down, and gamespot shut down. It is used for that program. It is a pain.   Scott in Minnesota
rate3 It`s part of Gamespot DLX, it runs in the background and speeds up game downloads by using a peer networking. It hasn`t alerted Ad-Aware Se or Spybot S&D (spyware detection tools)  See also: Link   Dan
rate5 it slow downs ur pc and u will not be able to access many applications   Eric
rate0 moviephone uses this as part of downloading previews   max singer
rate2 khost.exe is a secure data delivery application by Kontiki Inc. which delivers data such as images and files to secure servers for sharing. Installed with Gamespot.com Secure Delivery   Charter Guy
rate0 it is connected with Download.com and the Secure Download feature. By shutting down Secure Download, KHost.exe terminated itself.   mky in maynard
rate0 Its in the folder that was put on my computer when I installed MoviePhone which I got thru AOL. MoviePhone uses it for secure plug and play for movie trailers. Unfortunately there's no uninstall for it in Add and Remove nor is there one in the folder. I went to the link below and found out its cleverly named Secure Delivery Plug-In. Good luck  See also: Link   Mike
rate4 causes video card to switch to 640 x 480 on boot up   John
rate1 Gamespot Secure delivery  
rate3 Its "Open Media Network" delivery manager by Kontiki  See also: Link   Rupert
rate3 Peer 2 peer secure delivery application bundled with sky by broadband.It`s used to download protected film and video files from sky .com.It also uploads protected files previously downloaded to your computer for distribution to other user of the service.It`s supposed to be secure and doesn`t allow access to other parts of your computer but i would be wary for now.   Davy W
rate3 i have this on my pc and its part of the sky by broadband download package it acts as a p2p service to easy congestion on the sky servers its not a windows file and not dangerous although it does allow others to d/l film files from your pc it also send secure info about your pc to sky wich could be a problem if you have sensative data on your pc so you need to limit where other people can share your files from.   fubar
rate5 You can block KHost.exe access to the internet with firewalls such as Zone Alarm   Nancy
rate2 Its also part of channel 4 (UK) new download movies/tv programs section, a clone of the Sky version, which I immediately removed when I found out I was being used as a peer to peer server for file distribution without asking my permission prior to installation , underhanded tactics, using my bandwidth to run their service   Steve
rate1 4 on demand uses it to download sucure video i don't think its a problem   Stuart
rate1 Sky Anytime - From what I can see, many legit applications use it to download their files such as games from gamespot.com and movies from Sky. It slows down your computer, but nothing dangerous   Nick
rate0 appeared on my system after i downloaded 4od (channel 4 on demand) so i assume its connected to downloading video files   chang buddha
rate2 Part of the 4OD service for UK TV On Demand (provided by Channel 4). Same as for Sky TV Broadband content...  See also: Link   Cy Bones
rate3 It only seemed to appear on my pc since installing Channel 4's "4VOD" video on demand program. I guess that stacks up with similar experiences of Sky broadband and AOL Moviephone etc.   David W - West Calder, Scotland
rate1 Used by 4oD - Channel4 on Demand in the UK  See also: Link   Andrew B
rate0 It's installed with 4OD, channel 4's on demand TV service. I was suspicous at first but can't say it's caused any problems   Matt
rate4 Kontiki peer-to-peer software component. Dangerous if you have any broadband caps or a fair use agreement with your ISP.   Karin in UK
rate1 It is used by the BBC for their recently launched iplayer for playing and downloading media content. it is located in c:\program files\kontiki\khost.exe, within this folder there is also an "iplayer_live" folder which indicates the usage  See also: Link   Jonathan Gray
rate1 Yep a download connected service as it is also linked to 4OD, an on demand service from Channel 4 in the UK. The one issue users seem to be having is that the 4OD app is not best coded (still beta) and Khost.exe which relates to Kontiki in this instance uses a lot of bandwidth for the downloads.  See also: Link   Michael
rate1 It appeared as a result of installing the AOL HI-Q Video Delivery Manager.  See also: Link   Mike
rate3 Gets installed with Channel 4's 4OD   Mike
rate3 KHost appeared on my PC after I installed 4onDemand, which is software to permit the download of Channel 4 TV programs. I guess it's harmless, but I'll turn it off via MSconfig until I need to download from CH4.   Mike H
rate3 its part of 4od (channel 4 on demand) - and helps run/use the kservice.exe and khost.exe   HOOD
rate1 It arrived after I installed Channel4 on demand software   Gavin
rate3 Its installed as part of the 4od - Channel 4 On Demand service.   Welb
rate3 it is installed with 4od and allows the tv streamin program to download tv clips for watchin offline at later point. is tottaly pointless as can u acctually start up when you run 4od, so just remove it from the start up   Sir Python
rate3 Showed up after install of Hiqvideo for AOL video-- Not sure if its the culprit but my laptop took several minutes to startup or come out of stand by after install.   o51r15
rate1 Is the multimedia host/service process required by Channel 4 On Demand, BBC iPlayer. Also KService.exe is used.   Rabi Sultan
rate3 Looks like it also comes with the BBC's iPlayer too.   Steven SDF Sulley
rate1 bbci uses it for secure data delivery. Totally harmless.   Alex
rate4 I found it eating my CPU cycles and slowing everything down. It came bundled with Channel 4 on demand and it's more trouble than it's worth   John
rate3 Runs for both Channel 4 and BBC iPlayer - stop process in Task Manager causes no probs at all   Rich
rate3 I think it came with BBCi player   Ross m
rate1 Khost.exe is part of most video sharing applications which is used to securely download to your hardrive.   Jake
rate3 Used for Sky Broadband, BBC iPlayer and 4od. All used for downloading.   Dj23
rate0 Also used with Sky's 'Live TV' service. Harmless.   Tristan
rate1 it came with BBC i-player   Andy
rate3 It is used to streams video content for apps such as BBC iplayer, channel 4 4OD, Sky Player etc.   sauro
rate1 its by sky to help distrobute their tv programs and such. a p2p system if you will!   David Miller
rate3 It seems to be necessary for peer to peer sharing sites like the BBC iPlayer. But you don't need it if you just watch online streaming. If its worrying you remove it or reinstall one of the players   Mycroft
