*Previous relevant post: Avast! Messed Up the Wireless Connection on Laptop Too.The correct way to start Windows XP in safe mode:
Using the F8 Method
1. Restart your computer.
2. When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
3. Select the option for Safe Mode using the arrow keys.
4. Then press enter on your keyboard to boot into Safe Mode.
5. Do whatever tasks you require and when you are done reboot to boot back into normal mode.
Take a look at starting all types of Windows in safe mode for more information. Immediately after the Avast anti virus un-installation, my sister’s laptop regained normal functions. Avast anti virus needs to be more user-friendly, not to mention computer friendly as well!
