Windows Firewall
A firewall is included as part of the Windows 7 installation. If you already have a personal firewall on your computer (ie. you have deliberately purchased a program such as Zone Alarm), please either disable it or the Windows Firewall.
If you had a firewall included in a program that you have uninstalled as part of these instructions (ie. Norton Internet Security), please make sure that the Windows Firewall is switch on by following the instructions below and selecting the On, rather than the Off option
If you have not purchased a separate firewall, skip this section and go to Setting Passwords on Windows 7

If you have your own personal firewall, and wish to use it, rather than the Windows Firewall, please follow the instructions below to disable the Windows program. If you are unsure, check with the Computer Office (B2) before making any firewall changes.
Click on the Start button Click on Control Panel Click on Windows Firewall
To switch off the Windows Firewall, click on Turn Windows Firewall on or off (left pane)

Enabling Ping when using a firewall
The Computing Service runs a friendly probing service on all computers on the University network to make sure that they are not running anything that could be a security risk. One of the first probes sent is a ping – a test to see if your computer is working. If you have a firewall your computer must be set up to respond to a ping. On Windows 7, this is set a little differently:
Click on the Start button Select Computer
Right click on the University shield icon and select Open Double click the Config folder
Right click the file Set_Ping_On.bat (the .bat may not appear if you have your file extensions hidden) Select Run as administrator from the drop-down list
A window labelled c:\windows\system32\cmd.exe will appear When prompted, click a key on your keyboard to close the window
Setting Passwords on Windows 7
With so many people using fast Internet connections, such as the Murray Edwards' network or broadband at home, it is
important that computers are password protected to ensure that no one can access them when they are switched on. It is dangerous to assume that no one will notice you or attempt to hack in to your machine; programs have been specially written to look for unprotected computers.
Setting your own password
Click on the Start button Click on Control Panel Click on User Accounts
Click on Create a password for your account
Type your password of no less than six characters and preferably a mix of letters and numbers, in the New password box

Click on the Create Password button You have now set yourself a password
Repeat the above for all accounts on your computer that do not have a password
Switching Off Remote Assistance
Remote Assistance is a feature available under Windows 7 that has been designed to allow others to log on to your computer to provide you with assistance if you have a computer-related problem. Unfortunately, this feature could also allow access to unwelcome individuals and so it is better to turn this feature off. To do this:
Click on the Start button Click on Control Panel Double click the System icon
Click on Remote settings (left hand bar)
Make sure that Allow Remote Assistance connections to this computer is not ticked. If there is a tick in the box, click on the box again to remove the tick

Microsoft’s Antispyware Program
Microsoft Defender, which comes pre-installed on Windows 7, is a free program that helps to keep your computer free of spyware (a program that is installed without your knowledge to monitor or block your network access). Defender will
constantly monitor for changes to your computer, sometimes popping up message boxes to warn you of changes, sometimes asking for permission for changes and additions. If a message box appears asking for permission for a file to be amended or added to your computer, and you have not actively chosen to install a program, select Deny from the options given to help protect it from spyware. If you are in doubt, email the Computer Office at [email protected].
Running a spyware scan
Microsoft Defender constantly scans for spyware, however, if you are concerned that your computer is infected, follow these instructions
Click on Start, Control Panel, Windows Defender
If a message appears that the program is turned off, click on the link to turn it on If appropriate, click on the Check for updates now button
Once the program is up-to-date, do the following:
For a quick scan, click Scan button on the menu bar, or, for a more thorough scan click the down arrow next to the Scan button and select Full Scan
When the scan is complete, a window will appear either saying that your computer is fine, or it will display a summary of findings
Click OK to remove the list
If spyware has been found a further list will be displayed showing the name of the spyware, the threat level and recommended actions
To view information about an entry, click once on the spyware name and details will appear in a blue box to the left of the screen
What to do if spyware is found
Working on the assumption that all spyware on your machine has been put there without your express consent or knowledge, the College recommends that you remove any spyware found on your computer. To do this follow these instructions:
If the Recommended Action next to a Spyware item shows Ignore, click on the down arrow and change it to Remove Do this for all Ignore entries on the list
At the bottom of the screen click in the box next to Create restore point to ensure that if anything is removed in error, it should be possible to get it back
Click the Continue button
A window will appear confirming that you want the system to make the changes you selected (in this case, remove the spyware) - click Yes
Prior to removing the items a dialogue box will appear confirming that the system will create a Restore Point
Once this has been created a new dialogue box appears showing the various stages of the spyware deletion on a per spyware entry basis
Once the items have been removed a dialogue box will appear requesting a reboot to complete the deletion process Click Yes to reboot immediately
Microsoft Phishing Filter
Phishing is a criminal activity whereby “phishers” attempt to fraudulently obtain sensitive information such as passwords, credit card details, etc. by pretending to be a trusted individual or business, such as a bank. The Microsoft Phishing Filter attempts to establish whether a web site you are visiting is genuine by comparing the address of the link to the address of the link’s actual destination and warn you should there be a disparity.
Start Internet Explorer
When the Microsoft Phishing Filter appears, select the option Turn on automatic Phishing Filter (recommended) (next to the green shield)
Click the OK button
