I have sent the following to Zone Labs support.

"C:\Windows\Internet Logs\vsmon_on_demand (date) full dump file
Every boot of windows creates this file plus a Zip file of the previous vsmon_on_demand. This slows bootup to a crawl. It also creates huge Internet Logs folder (1000's of MBs) depending on numbers of times you start windows.
This only occurs with Spybot Search & destroy resident "TeaTimer" running at startup. I assume there is some sort of a conflict between ZASS and TEATIMER.
This problem does not occur when running versions of ZASS 6.1.737.000 and earlier. Only the later versions 744.000 and 744.001.
Would you please look into this and see if there is a solution other than having to go back to ZASS 737.000.
All my installs of ZASS have been good and as a long time user I am very pleased.
Thankyou for your time."

As I rely on TeaTimer with ZASS I hope someone can resolve this issue.
