In a nutshell I would not recommend the use of this program. The issue can be resolved without the use of miracle programs like this.
Because the Global Logger session used by BootVis is triggered by registry entries, it runs every time that the entries appear in the registry, which has resulted in some users seeing hard drive space exponentially decreasing due to the size of the trace.log file (in C:\WINDOWS\System32\LogFiles\WMI).
PSI Secunia is another one of those programs like Driver Mechanic. In most cases it won't give you the correct info and you will have to pay for the program in the end to egt it to download and install the updated driver. Personally Microsoft's Window Update will be a better method to keep your system patched with security updates. As far as your software and hardware a visit to the manufacturer of the hardware and to the author of the programs once a month will be a lot safer way to keep them up to date.
Disk Check passmark a good ideal but again another program that does not need to be running all the time. If you really want to keep this program I would run it when you need it and not allow it to run in real time mode.
