Removing Infections From Your System
BOOTSCAN.EXE, the command-line scanner that comes with the
Emergency Disk, will make four scanning passes to examine your hard
disk boot sectors, your Master Boot Record (MBR), your system
directories, program files, and other likely points of infection on all of
your local computer’s hard disks.
NOTE:
McAfee strongly recommends that you do not interrupt the
BOOTSCAN.EXE scanner as it runs its scan operation. The
Emergency Disk will not detect macro viruses, script viruses, or
Trojan horse programs, but it will detect common file-infecting and
boot-sector viruses.
If BOOTSCAN.EXE finds a virus, it will try to clean the infected file. If it
fails, it will deny access to the file and continue the scan operation. After
it finishes all of its scanning passes, it shows a summary report the
actions it took for each hard disk on the screen. The report tells you:
•
How many files the scanner examined
•
How many files of that number are clean, or uninfected
•
How many files contain potential infections
•
How many files of that number the scanner cleaned
•
How many boot sector and MBR files the scanner examined
•
How many boot sector and MBR files contain potential infections
If the scanner detects a virus, it beeps and reports the name and location
of the virus on the screen.
6. When the scanner finishes examining your hard disk, remove the
Emergency Disk from your floppy drive, then shut your computer off
again.
7. When BOOTSCAN.EXE finishes examining your system, you can either:
•
Return to working with your computer.
If BOOTSCAN.EXE did
not find a virus, or if it cleaned any infected files it did find, remove
the Emergency Disk from your floppy drive, then restart your
computer normally. If you had planned to install VirusScan
software on your computer but stopped when Setup found an
infection, you can now continue with your installation.
•
Try to clean or delete infected files yourself.
If BOOTSCAN.EXE
found a virus that it could not remove, it will identify the infected
files and tell you that it could not clean them, or that it does not have
a current remover for the infecting virus.
