Other users (in other forums) are reporting that this Trojan brings with it the ZeroAccess rootkit, so maybe there's additional malware on your system. Could be the rootkit is replacing the Trojan every time it gets deleted. Try running Rootkit Remover (from HERE) and Stinger (from HERE) and if that doesn't do the trick try HitmanPro, which seems to have a good success rate with the latest ZeroAccess variants.
Latest information on the Trojan (which is just your average vehicle for other infections) is HERE
