VZE26WYC  I to loose all my personal data. Passwords for everything reentered. It also seems to have caused a problem with Time Machine and it’s backups?  
(Version 1.9.2)

VZE26WYC  It seems that I have had ‘Macaroni’ always in the system preferences do it’s thing. I look at the logs and it does do everything it says it does. All the updates are free. Thanks for the very good product...  
(Version 2.1.1)

VZE26WYC  My system was brought to complete halt [froze] as well. I had to manually restart. Any suggestions?

OS 10.5.2 I-Mac 2.8  
(Version 1.9)

VZE26WYC  I have had Norton for years and with Tiger it takes hours to scan the drive. I ‘switched’ to VirusBarrier, drive is scanned in minutes! Yes I called Symantec and the man from India wanted to have remote access to my computer-NO WAY.  
(Version 11.0)

VZE26WYC  There are those who will not go to 10.5 so this is good way of supporting that segment. You have to put your goods on the street before anyone will buy. I am happy to see ‘bundles’ offered .  
(Version )

VZE26WYC  Sorry but I have had no problems with TT Pro 4.1.1! As a matter of fact it does both of my drives [internal/external] at the same time.I only defrag my files never the entire drive. After that "security update" bug I use TT and it fixed what ever the problem was. Again I am sorry I can not knock TechTool Pro v4.1.1  
(Version 4.1.1)

VZE26WYC  I have use TechTool Pro for a long time now. This is by far the best version yet!

It took is seemed like years to check files and to do maintenance. Now this version does the routines in minutes.Just follow the directions on the up date.
