 Check Open Ports -http://www.auditmypc.com/firewall-test.asp

How to block Ports
 Block Ports
 Control Panel>System and Security> Windows Firewall
 Advanced Settings
 See inbound and outbound rules
 Create your own rule

How to know if there is spyware?
 Endless pop-up windows.
 Redirected to other websites automatically.
 Random Windows error messages .
 Computer suddenly seems slow.
 New and unexpected toolbars appear in web browser.
 New and unexpected icons appear in the task tray.
 Browser's home page suddenly changed.
 Search engine your browser opens has been changed.

 Don't click on links within pop-up windows
 Be careful while installing free software , never forget
to read user agreement.
 Block pop-up windows and cookies by adjusting
browser preferences.
 Be aware of unexpected dialog boxes asking -Do you
want to run a xxxx program . Always select "no" or
"cancel," or close the dialog box.
Prevent Spyware Installation

Remove Spyware
 Spyware copies several files to different directories and
changes the registry. Use a spyware remover - a
program dedicated to removal of sypware.
 Run a legitimate product to remove spyware e.g
Ad-Aware, Microsoft Window Defender, Webroot's
SpySweeper etc.

Preventive Measures-II
 Prevent Identity Theft-Beware of phishing scams - a form of fraud that uses
email messages that appear to be from a reputable business (often a financial institution)
in an attempt to gain personal/ financial account information. These often do not
include a personal salutation. Never enter personal information into an online form you
accessed via a link in an email you were not expecting. Legitimate businesses will not ask
for personal information online.
 Intrusion Detection Software/Device
