Clean Booting your System
NEVER attempt to carry out a clean-up operation if there is a virus in memory. Always power-off and boot from a clean disk to avoid running anything from a virus infected hard disk and making things worse.
To do this you'll need a bootable system disk for your PC. Things to think about include:
- A bootable system disk should allow you to access the hard disk of your PC. This may mean creating several system disks if you have a variety of PCs with different operating systems - DOS, Windows 95, Windows 98, Windows NT, etc. These disks are often referred to as Emergency Restoration Disks, or Startup Disks.
- You may need to load one or more device drivers in order to access your some PC¿s resources. If you have a network, you should create a disk containing clean copies of the relevant network drivers to enable you to connect to the network without running any programs which may be infected. This can get complicated so contact IT if you need assistance.
Your system disk(s) and other utilities should be created in advance of any virus outbreak. If you end up infected, it takes no time to discover that you lack the tools necessary to deal with it. IT recommends that you put together a set of emergency tools in advance of any virus infection, if not individually, at least something by department. Your virus "crash kit" should be kept up-to-date and your office should know how to use it.
