Ok,
Quick 5.08 Update has been done to fix the Quarantined files. Please make sure that you download it from here
http://www.mtu.com/upgrades/hoster.htm
The only way to find out if it is the correct version or not, is you must install it, then Open Hoster. Once you are in Hoster, go to the Help Menu\About Hoster here you should see 5.08. Notice the Period after the 8. This is the only place, that it will show if you have the fixed version or not.
