"As of February 2005, two major problems exist with this software, it
adds a huge latency into the windows system sometimes causing
processes to delay loading by as much as 10 seconds. While this is
tolerable for some people, it is a huge headache for others. The other
problem is that there is a known memory leak in the program causing it
to eat away windows memory over time until the system runs out of
memory.
When Microsoft bought the company that made this product there was
another company called Sunbelt Software that made a similar product
that was based on the same programming (There was a deal between
Sunbelt Software and Giant Company).
In our lengthy communication with Sunbelt Software in February 2005,
we were told that the Sunbelt Software product called was being
redesigned to eliminate the latency problem and to deal with the known
memory leak. There is no indication that Microsoft is addressing these
problems even though they have been reported."
