It’s so annoying when 3 hours into a virus scan, from a Rescue CD the laptop just decides to power down. A whole host of malware found but not removed, so it has to be done again. Before anyone says, the power lead WAS plugged in and the power was on..oh well, I’ll try a different CD.
For anyone unfamiliar with boot CDs, the idea is you can load clean software from the CD to perform a virus scan on an infected disk. If you start (Windows) from an infected hard disk, the infection may be able to hide itself, or use various blocks to prevent the user, or an antivirus tool from removing it.
