How System Restore Works
As mentioned, an Acer system restore disc can be used to bring a system back to its original form that came from the manufacturer. A system restore disc is different from the built in system restore function of an operating system as the disc will completely remove everything from the hard drive. You can think of a system restore disc as another form of reformatting a computer's hard drive. This is the primary reason a user should save this option as a last resort, as it will wipe everything from the hard drive.
Before you use an Acer system restore disc, make sure you have current back up copy of everything on your computer. Be sure to put this copy in another place, such as an external hard drive or secondary hard drive. It is also a good idea to have all the programs and applications near your computer so that when the process is finished, you can begin to reinstall all your programs.
Place the restore disc in your CD/DVD ROM tray and then restart your system. Your computer will go through its normal process of starting, however at some point, it will discover the disc in the drive and ask that you press any key in order to boot from the disc. If you do not get this option, your computer may not be set up to boot - or read - from a CD. This can be changed within your BIOS settings by hitting the DELETE key at the opening screen and then locating BOOT OPTIONS.
When you have allowed for the computer to read from the restore disc, follow the instructions to begin clearing your hard drive. This will ensure that the virus - and everything else - is wiped clean. Again, this method should be a last resort, after all else fails.
