Events possibly related to antivirus software and/or Firefox

[EnumaElish]

On my XP-pro (SP2) operated machine I have come across messages in the event viewer such as:

A thread in process c:\PROGRA~1\mcafee.com\vso\mcshield.exe took longer than 30000 ms to complete a request.
The process will be terminated. Thread id : 1776 (0x6f0)

The McAfee.com VirusScan Online Realtime Engine service failed to start due to the following error:
The system cannot find the file specified.

In addition, when I let McAfee Virtual Tech scan the PC it returned the following:

Virtual Technician Report - Personal Firewall Plus
Issue(s) detected
Missing files
C:\Program Files\McAfee.com\Agent\app\MPF.adf

Does anyone have an idea as to whether these are related, and how to solve each?

Looks to me like you're missing some mccaffee files. Try reinstalling it.
