Using the Command-Line Scanner

What can you scan?

What can you scan? 

„

File types scanned by default.

 

The following file types and many other common file types that are susceptible to 
infection are scanned by default: .BIN, .COM, .DLL, .DOC, .DOT, .EXE, .HTM, .INI, 
.OVL, .RTF, .SYS, .VBS, .VXD, .XLA, .XLS, and .XLT. 

„

Archived and compressed files recognized by the scanner.

 

You can scan compressed and archive file formats which include .ARC, .ARJ, .CAB, 
Diet, .GZIP, LZEXE, .LZH, PKLite, .RAR, .TAR, and .ZIP files. 

The scanner detects and reports any infections found in any compressed or archive 
file. The scanner can also clean files in .ZIP archive format. If you have access to 
Windows, you can clean certain infections from compressed files using VirusScan 
for Windows software. 

You can use the options 

/UNZIP

 and 

/NOCOMP

 to configure the scanner to handle 

compressed files. These and other scanning options are described in the tables 
from 

page 25

 to 

page 30

. 

„

Any potentially unwanted software, cookies and registry entries

. 

The scanner detects and reports these items, enabling you to remove them if 
necessary. 

Scanning diskettes

Diskettes pose a threat because many viruses infect computers when a computer 
‘boots’ from an infected disk, or when users copy, run, or install programs or files that 
are infected. If you scan all new disks 

before first use

, you can prevent new viruses 

entering any computer system. 

Always scan all disks you use. Do not assume that disks received from friends, 
co-workers, and others are virus-free. Disks can also pose a threat even if they are not 
bootable. Therefore, we recommend that you check that your disk drives are empty 
before you turn on your computer. Then your computer will not pick up a boot-sector 
virus from an infected disk that was inadvertently left in a disk drive.

1

Using the 

CD

 command, change to the directory where the scanner was installed.

2

Type: 

SCAN A: /MANY

 

3

Insert a disk into the A drive, and press E

NTER

. 

The program scans the disk and displays the names of any infected files. 

4

Remove the scanned disk from the A drive.

Repeat 

Step 3

 and 

Step 4

 for all disks that you need to scan. 

Note

If the scanner detects a virus on this disk, it runs the command-line option that you 
chose for dealing with the virus. See 

page 40

 for details on removing viruses.
