UPH cleanup - part of Anti-malware Kit in Malware Prevention & Security Posted January 11, 2009 · Report reply While I'm not fully aware of the exact methods UPHClean uses, I do know it is a completely safe program. After all, it's a part of Windows Vista by default. Is "Sanity Check" the name of the program reporting this? Yes, that's the name "Sanity Check" I use it to check for hidden rootkits, but I should clarify, the program states that as a general rule programmers should not use that mehtod of hooking unless they are very very good, so as you say it's part of vista so probably no issue there. It was merely pointing out the methods which it used should only and can only be done by extremely good programmers, otherwise it is probably some sort of Rootkit activity of a general nature which could cause more problems as it could very easily make windows unstable.
