TinyAntivirus

TinyAntivirus (TinyAv) is an open source antivirus engine designed for detecting polymorphic virus and disinfecting it. Now, TinyAv can detect and disinfect Sality polymorphic virus. In the future, I will deveplop some modules for removing other polymorphic viruses, such as Virut or Polip.

License

This project is released under the GPL2 license.

Requirements

Microsoft Visual Studio 2015
zlib 1.2.8 or newer
unicorn-engine 0.9

Quick start

Clone the repository: git clone https://github.com/develbranch/TinyAntivirus.git.
Build: Core engine, Console and scan module.
You can see Release Directory. Change the Release directory and run TinyAvConsole.exe.

Usage

TinyAvConsole.exe [options]

Option	Meaning	Default value
-e	plug-in directory	current directory
-A	Archive scan depth	-1 : any depth
-D	scan depth	-1 : any depth
-d	path to scan
-p	file pattern	.
-s	max file size in bytes	10 * 1024 * 1024 (10 MB)
-m	Scan mode: Kill-virus (k) or Scan-only(s)	Kill-virus (k)
-h	Show usage

You may scan all directories and files by using default values.

Example: Scan for all files (include ZIP files) to detect and disinfect virus. ZIP files which contain virus will be deleted.

Contribute

If you want to contribute, please pick up something from our Github issues.

I also maintain a list of more problems in a TODO list.

I have only one Sality sample to develop Sality killer module. I think there are many variant types of this file infector. Please send me samples which TinyAv can not detect or other kinds of polymorphic viruses. Thank you.
