Hi,

Both workstations on my home network are suffering from what appears to be a rogue MSIExec process consuming up to 100% of system resources, causing them to run very slowly. I may be mistaken, but I have recently replaced Kaspersky with BitDefender on both machines, and I am concerned that this change is causing or has led to my current problem. The HijackThis log from the one machine is:
