We use TrendMicro office scan in our windows environment. The workstations have XP professional. Many ( but not all ) off the pcs show this error when loading TrendMicro. It pops up 8 times and when we close it it doesn't come back until someone else signs in or the pc is rebooted. It is very annoying though. We have uninstalled and installed the program. In some cases even when we have uninstalled the error still comes up. It is "ntrtscan.exe has encountered an error and needs to close"
Version 7 of Office Scan
I have attached a screenshot of the error as well.
