your computer from malicious communications. By default, this firewall is

• Completely disable the firewall as follows. Note this can leave your
computer vulnerable to attack so consult your computer documentation or
IT administrator if you are unsure:
a. Open Control Panel followed by Computers.
b. Right click My Computer and select Security Center
c. Select Windows Firewall
d. On the General tab choose option Off
