HpM3Util.exe ?? Anyone knows how to get it out?

I heard someone mentioned it as a Trojan horse virus. I don't have a clue how to get it out. Tried many security tools. They all failed. Well, some of them did make this malware stop for a while. Suggestions, please???

To remove this tricky threat thoroughly, all its related processes, files and registry entries have to be eliminated all together. It may also modify your start-up entries. Better check all these places.

Click Start menu, type: msconfig in the Run box; click Ok to open the System Configuration Utility; Disable all possible startup items generated by this virus.
