Freeware For Us

VirusScan Command Line utility is a program that provides a way to quickly perform virus-checking using the command prompt. It is an alternative to scanners that uses windows graphical user interface (GUI). It is effective and provides quick solution against viruses, trojan-horse programs, and other types of potentially unwanted software.

If your one of the geeks or IT experts that recently noticed it’s command-line scanner utility (scan.exe) is gone or missing at it’s SuperDat file. Then here your are: Where can you find and download McAfee VirusScan command-line tool?

http://www.mcafeeasap.com/downloads/CLS/vscl-w32-6.0.1-l.zip

to update the tool with the latest virus definition, look for the filename that is of the format avvdat-nnnn.zip, where nnnn is the DAT
version number.

Create a folder and just overwrite the files.

The current release version includes the latest technology in anti-malware providing improved detection rates, smaller file downloads, Multi-threaded scanning support and XML support for easier processing of scan results.

It provides the optimum protection for your computer and network using advanced heuristic analysis which detects previously unknown macro viruses and program viruses.

McAfee Information about the command line-utility

Scanning NTFS streams
Some known techniques of virus file infection is adding at the beginning or the end of a file. Streams might contain viruses and exploit the NTFS multiple data streams feature in Windows operating systems.

VirusScan command-line utility can analyze and detect a stream virus by specifying the full stream name, or including /STREAMS and specify using wildcard characters ? and *.

Heuristic Analysis

The scanner uses two techniques to detect viruses — signature matching and heuristic analysis. A virus signature is simply a binary pattern that is found in a virus-infected file. Using information in the DAT files, the scanner searches for those patterns. However, this approach cannot detect a new virus because its signature is not yet known, therefore the scanner uses another technique — heuristic analysis.

/ANALYZE : Turn on heuristic analysis for programs and macros.

/PANALYZE : Turn on program heuristics.

/MANALYZE : Turn on macro heuristics.

To clean your computer using McAfee Command-line

Shut down your computer and boot it into Safe Mode.

Scan your disks after the boot. At the command prompt, type:
SCAN /ADL /ALL /CLEAN /WINMEM /PROGRAM

Other commands that you can use:

To scan all folders and subdirectories

SCAN /CLEAN /ALL /RECURSIVE e:

To scan drive C including streams with advance heuristic analysis

SCAN /CLEAN /ALL /SUB /ANALYZE /STREAMS /WINMEM c:

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.
