It's fine to follow directions of someone like me and install everything
that is suggested, but how do you know for sure if you have been
instructed to install the right products or that they are set up to
protected your computer? By checking your computer's vulnerability with
the following utilities you can see for yourself your computer's
vulnerability and how to make any changes needed to secure your system.
Shield's Up! When you
click on this link you will be taken to a page that will explain to you
what is about to happen. When you are finished reading and ready to see if
your computer is vulnerable or not click on the Proceed button. On the
next page you will find a table called Shields Up!! Services. The average
user will want to try the top row of tests. File Sharing,
Common Ports,
All Service Ports, Messenger Spam and Browser Headers will all test your
computer and report back to you if your computer is vulnerable and how to
make the changes to protect your computer.
User Specified Custom Port Probe and Lookup Specific Port Information are
for the advanced user.
When you run the File
Sharing test what you ultimately want to achieve is shown in this
this screenshot. If someone
attempting to access your computer cannot find any sign of life then they
are not able to access it.
When the Common Ports
scan is run you want to achieve a full stealth report as shown in
this screenshot. The utility will
probe all of the common ports of your computer to see if it is able to
access it. If it fails your will receive a TruStealth Analysis. The text
version you should see is below.
