This document refers specifically to Microsoft Windows XP Home and Professional and Internet Explorer 6. The same principles apply to Windows 95\98\ME\NT4.0 and 2000.
2. Ensure that Windows Update is run at least once a week to download the latest important security hot fixes.
Once viruses have been removed using a good virus scanner there might still be other spyware programs installed on the computer.
This can be done as follows.
Load Internet Explorer.
Select the menu item Tools\Internet Options...
Press "Delete Files..."
Tick "Delete all offline content", press OK.
This may take a few minutes if the cache is very large or has never been cleaned.
It may be a good idea to set the cache size to a lower value, such as 100Mb to save disk space and to make cache management quicker in the future.
Windows uses a percentage of the hard disk space to set this value by default, and it is usually extremely large and slow to delete over time on large modern drives.
Press "View Files..."
Select the menu item "Edit\Select All..." then press Delete on the keyboard.
When done, press OK.
Press the right mouse button and Save Target As... on the link that says "stand-alone version of CWShredder".
Download and run the program.
Press "Fix ->"
CWS Shredder will display this message box.
Close all instances of Internet Explorer, Windows Media Player and MSN Messenger then press OK.
If all is OK a clean report will be displayed. If not, CWS Shredder may need to reboot the computer to remove suspicious files from memory and delete them from the hard disk.
Download and install the latest free version of Spybot - Search & Destroy 1.3
Download and install the latest detection updates
Load Spybot Search and Destroy
Press "Check for problems"
This will take several minutes to run and remove all the suspicious files. Follow the on screen instructions.
Windows may need to reboot to allow Spybot Search & Destroy to completely remove malicious programs that may be running in the background.
In general it is best to accept its recommendations.
Download and install HijackThis
HijackThis is an advanced program to stop certain suspicious programs being loaded when Windows starts, remove browser hijack objects (BHOs) and other system and web browser hooks.
If there are any suspicious items listed such as services or programs which should not be there, and are not recognised system objects then tick them and press "Fix checked" to allow HijackThis to remove the item.
HijackThis writes a log so that deleted registry settings can be restored later.
Ad-aware Personal is like Spybot Search & Destroy. It can be good to double check incase the latest definition files contain details of a new threat.
In general Spybot Search & Destroy is quicker and easier to use.
