**It is very important to run the update for each program before running the app/s
to be sure you have the latest definitions.**
Run the programs in Safe Mode after assuring you have shut down all running tasks
except explorer or systray and all apps are fully up to date.
Remove your Temp Internet files: Right click IE. Under the General tab click Delete
Files, put a check in Delete all Offline..., click OK and close when finished.
Delete all files in c:\windows\temp.

hap-hazardly without knowing what they are can/will create a royal mess. Read the
