Security

Setting up Safe Passwords

Passwords add a level of security to your computer. When sharing a computer with others, your customized settings, computer programs and system resources are more secure when you assign a password to your user account. Some passwords are better than others. A password that is easy to guess or break into is described as WEAK. You can help to protect your information by choosing a STRONG password. Strong passwords are described in:

microsoft.com/security/online-privacy/passwords-create.aspx

To Set or change your password

When you are logged in:

• Click > then select Control Panel • Select User Accounts

• Click Create a password, or Change the password • Type the new password

• Type the new password in again to confirm

• Type some descriptive or meaningful text to use as a password hint to help you remember your password

• Click Create or Change Password

Dealing with Viruses and Other Nasties

This section briefly describes computer viruses and how to protect your computer by using Anti-Virus software.

What is a computer virus?

A computer virus is a program that has been written with malicious or mischievous intent. This is called a virus because it will usually include some mechanism to copy itself to other computers and therefore spreads in a similar way to a biological infection.

A combination of anti-virus software and regular updating of Windows and Office will help to protect your computer.

Anti-Virus software has to contend with new types of virus appearing daily. So, it is important to regularly update your anti-virus software definition list (not the software itself but the list of all viruses). Anti-Virus software on IT Services computers has been configured to update its definitions list daily.

Installing MSE Anti-Virus Software (FREE)

Microsoft Security Essentials (MSE) is the free antivirus software that we recommend for home users.

Before installing any Anti-Virus software please ensure that you do not have any Anti-Virus software already installed. Running two Anti-Virus packages could cause your PC to become unstable but there are special removal tools that you can use to delete Anti-Virus software that you no longer need.

To remove Anti-Virus software, see the section on “Removing Unused Software”. We recommend that you disconnect your computer from the Internet before uninstalling one antivirus software product and installing another. This is because your computer will not be protected while this is being done.

You can get a copy of MSE Anti-Virus software, and step-by-step installation instructions, from the Microsoft Website at:

Dealing with Spyware Housekeeping Your PC

Dealing with Spyware

Several other types of malicious programs are not detected by anti-virus software; these are known as malware or spyware. These have become common on the Internet and many computers have become infected with them. These programs can compromise your privacy and cause your computer to run slowly.

Malwarebytesand SpyBot are two tools that can help you to get rid of spyware. Free versions are available for personal use, see:

sussex.ac.uk/its/services/programsandsoftware/software/owncomputer

Notes:

To install Malwarebytes click on the link to download the free software, select Save, then when the download is complete run the software to install Malwarebytes on your PC. You are recommended to run this program regularly to check your PC for

spyware.

When installing Spybot, you don’t need to donate, just click the download button for the free version. There are several download sites that you can select. Select the site, select Save, then when the download is complete run the software to install Spybot on your PC. You are recommended to run this program regularly to check your PC for spyware.

Configure Windows file names

Windows often hides the full names of files. This can make it more difficult to spot files that might be unusual or harmful. You can make a simple change to see the full file names in Windows 7:

• Click > then select Control Panel • Click Folder Options

• Click the View tab

• Scroll down to the line Hide

extensions for known file types and make sure the box next to it is unchecked

Installing Windows and Office Updates

When Microsoft becomes aware of problems, especially security concerns, they release updates (also called patches) to fix them. If you install Windows updates regularly, you will avoid many potential problems.

If you haven’t installed updates before, they will take several hours to download. You can decrease the amount of time necessary by installing the latest service pack first. We strongly recommend that you install Service Packs which has many security enhancements. A service pack for windows 7 will be available in 2011, see:

windows.microsoft.com/en-us/windows/downloads/service-packs

Once you have installed the latest service pack, you must visit the Microsoft Update Site at:

update.microsoft.com

And get the updates that have been released since the service pack was issued. Details of how to find out which version of Windows and which service pack you have currently installed can be found in this booklet in the section called “Versions of Windows and Office”.

Setting up to automatically download future updates

Once you have caught up with current critical Windows updates, you'll need to install any new ones that come out. You can do this manually, or you can set up your

computer so that it happens automatically. Your computer will check for updates, download them, install them at a time specified by you, and reboot all on its own. If your computer is turned off at your selected installation time, it will perform the installation the next time it is powered on. To set up the automatic updates, follow the instructions at:

windows.microsoft.com/en-US/windows7/Install-Windows-updates

Housekeeping Your PC Performance

Performance

You should periodically store (archive or backup) or throw out documents and files just as you would with a paper based filing system. Your computer will then run more smoothly.

Disk Cleanup

The disk cleanup program attempts to consolidate the removal of all unused and temporary files. This is useful but you should also make regular checks yourself, even if only to familiarise yourself with the structure of the file system on your hard disk (the C drive). To delete the files manually see the information on the next page.

• Click > then in the search box type Disk Cleanup

lick on Disk Cleanup in the programs window, the following window will appear:

• Select the C: drive, click OK, then Disk Cleanup will calculate how much space you can save and display the following window:

• Each tick box can be selected to indicate the areas of the disk you wish to delete unused files from, tick the boxes next to:

Temporary Internet Files Temporary files

Recycle bin

• Click OK to delete the selected files

Deleting Temporary Internet Files

Finding and Deleting Temporary (TMP) files Housekeeping Your PC

• Start Internet Explorer

• From the Tools menu, choose Internet Options • Under the General tab, click the Delete button

• Now you can delete you temporary internet files, cookies, history, form data and passwords that have been saved by Internet explorer

• Click Delete

Finding and Deleting Temporary (TMP) files

Temporary files have the suffix “.tmp”. They are created temporarily by Windows programs and Utilities, such as Word and are normally deleted when the program is closed down.

Temporary files should be automatically stored in a TEMP directory. However, it’s possible with Windows that a number of TEMPorary locations have been set-up for each user. To find and manually delete these files:

• Click

• In the search box type %temp%

An explorer window will appear with the names of all folders and files on your PC, which contain temporary files. You can then select any file or folder you want to delete and press the <<delete>> key on the keyboard to send the file or folder to the Recycle Bin.

Emptying the Recycle Bin

When you delete files, they end up in your Recycle Bin, to remove them completely: • Double click the Recycle Bin icon on your desktop

• Check that all files in the Recycle bin are either backed-up or no longer required

Housekeeping Your PC Performance

Disk Defragmenter

Files on a disk can become fragmented. This means that files may be stored in two or more chunks on different parts of your disk. This can slow down your system, as it takes longer to read and write files that aren’t stored neatly in one place.

The disk defragmenter takes fragmented files and puts them back together so that the hard drive doesn’t have to work as hard to get them.

By default Windows 7 Disk Defragmenter automatically defragments your hard drive(s) on a schedule for you. A normal computer user should never have to deal with the disk defragmenter in Windows 7.The Disk Defragmenter runs as a low priority task in the background without affecting the performance of the computer. To see, or modify the schedule:

• Click > then in the search box type Disk Defragmenter

• Click on Disk Defragmenter in the programs window • The following window will appear:

Checking the Hard Disk for Errors

Errors can appear on your hard disk and may affect performance. You can use the “check disk” tool to identify and possibly remove disk errors.

• Click

• Click Computer

• Select the local disk you want to check (C) • Right click, click Properties, click the Tools tab • Under Error-checking, click Check Now

• Click Continue

• To perform a complete check of your hard drive for errors check both options in the check disk window that pops up.

Removing Unused Software Housekeeping Your PC

Removing Unused Software

If you share your computer with other people or often install software to try-out, then you will find that your hard disk (however large) may become full. Computer games are particularly large, often requiring in excess of a Gigabyte of space. Consider regularly looking at the software you have installed and deciding if it is still required.

• Click > then select the Control Panel • Select Programs and Features

• Wait until your list of installed programs appears

• Select the program you want to remove and click the Uninstall button at the top of the window

• Wait for the program to be removed and follow any on-screen instructions You may receive a message that parts of the software (file or folders) could not be removed. This may be files that you have created yourself that were not installed by the software (installer). In the case of computer Games this will be ‘game saves’ i.e. information relating to your current status within a game. You may wish to back-up these files or remove them manually.

Manually Deleting a File or Folder

It is useful to be able to find files or folders on your computer to delete them manually. This is how to delete your program files using Windows Explorer:
