If I remember right, that is sold under OnTrack Systems or something? (Used to be Mijenix?)
IF I have the right software in mind...it rocks, In My Arrogant Opinion.
I mostly use Linux nowadays, but when I was primarily running Windows that was the system suite I used- antivirus was better than Norton or McAfee for me, and the registry utilities were excellent.
Note that I have only a short experience with it under WinXP as I mostly ran Win2k or NT 4.0- or even Win98.
There used to be two versions: one had the more basic set
AV
Diagnostic tools
Recovery tools
The other added firewall and some other stuff that I didn't use.
I did pay $40 for one version of it just for the av and resgistry optimizing stuff though, and it was well worth it.
I have no idea where my cds are now, but if you post a link to the one you are looking at, I bet I can ID if its the one I am thinking of.
