I am in the process of tuning a slow PC running Win XP. The first thing I did was to scan it with Malwarebytes. It found some malware that the owner's copy of Norton missed, and cleaned them up (see attached). I have scanned the PC 2 more times, and it came up clean each time.
I also disabled many of the startup programs. One other behavior I planned to cleanup was an alert window that appears after a user logs in and cannot be closed. It appears to be a Micosoft Windows message.
Title: Data Execution Prevention-Microsoft Windows
To help protect you computer, Windows has closed this program.
Name: Generic Host Process for Win32 Services
It appears to be triggered by the dumprep progam. There are two instances that are invoked at startup dumprep - u and dumprep -k. I've disabled them using msconfig and deleted their entries in the registry that start them. I've also disabled error reporting in System Properties. Once disabled, the message does not reappear, as I log off a user and back on. However, the next time the system is rebooted the message returns when I log on to any of the users. Please advise.
