    The link for this newest version game me the 3.0 build, not the 3.1.
    Iobit site doesn't even have this build up.

    Windows 8 x64 does not like this software at all, in fact it blue screens it on a fairly regular basis. Besides, their software is not all that good and it causes more problems than it fixes. If you use it and you like it and it works well for you, then so be it, otherwise find something else as there are several much better than this....This is slow, laggy and useless in my estimation.

    DKDude:

    Surely you aren't worried about spyware are you? An old Chrome plated Googleite like you? Maybe if you use IOBIT software a tin hat will protect you? You have posted several links for the paranoid people, seems to me you are one too?

    LMAO here :-)

    This good tool runs only at WinNT or hiher, not on 9.x!
