Ensure that your system is 'clean'before installing DefenseWall.
Any pre-existing malware or infected files on your computer prior to installing any
security software can still actively compromise or damage your system.
If you are not starting with a fresh system installation, do a full system scan with a
good anti-virus and anti-malware application. It may also be beneficial to do an online
scan with one of the anti-virus providers as a secondary safety measure.
