VirusTotal - Free Online Virus and Malware Scan

VirusTotal is a service that analyzes suspicious files and facilitates the quick detection of viruses, worms, trojans, and all kinds of malware detected by antivirus engines.

Why I like VirusTotal? Check out how many antivirus engines it used at one time: AhnLab (V3), Aladdin (eSafe), ALWIL (Avast! Antivirus), Authentium (Command Antivirus), Avira (AntiVir), Bit9 (FileAdvisor), Cat Computer Services (Quick Heal), ClamAV (ClamAV), CA Inc. (Vet), Doctor Web, Ltd. (DrWeb), Eset Software (ESET NOD32), ewido networks (ewido anti-malware), Fortinet (Fortinet), FRISK Software (F-Prot), F-Secure (F-Secure), Grisoft (AVG), Hacksoft (The Hacker), Ikarus Software (Ikarus), Kaspersky Lab (AVP), McAfee (VirusScan), Microsoft (Malware Protection), Norman (Norman Antivirus), Panda Security (Panda Platinum), Prevx (Prevx1), Rising Antivirus (Rising), Secure Computing (Webwasher), Softwin (BitDefender), Sophos (SAV), Sunbelt Software (Antivirus), Symantec (Norton Antivirus), VirusBlokAda (VBA32), VirusBuster (VirusBuster).

It is very useful when you download some unofficial patch. Actually I have used it to find several trojans my local antivirus program did not find.

Hint: Use it before you calculate and save file’s MD5 hash, if file was not downloaded from a trusted site.

Md5Checker pal - SafePack Backup Script - One-click backup solution

When you use Md5Checker, you may wonder, what should I do if I found anything broken? Can I restore it? Can I backup them easily and earlier?
There is a solution: SafePack Backup Script can backup your files with simply one double click. It will go through sub-folders recursely, only backup specified file types, will never backup any file duplicately (backup same file more than once), can set up password and compression level, and it is only 2K.

How to use:

1. Copy safepack.cmd to the backup folder of your setup files, e.g. E:\Setup Files.
2. (Optional) Open it using any text editor.
3. (Optional) Find and edit the following code:
   set _ext=*.dll;*.drv;*.exe;*.msi;*.sys;*.vxd
set _WinRAR=%ProgramFiles%\WinRAR\WinRAR.exe
set _password=password
set _compression=0
set _showLog=1
   _ext - File types you want to backup. Usually executable files as they may be infected by Virus, Trojan or Worm.
   _WinRAR - Full path of WinRAR. This script will call WinRAR to backup.
   _password - Set up a password that makes the backup stronger. This parameter can be empty.
   _compression - Set the compression level. 0 - Do not compress, fastest, 5 - The highest.
   _showLog - Whether show log or not. If 1, a notepad will popup with the log. Otherwise log will be saved to file and you can check it as you want.
4. Run this script. All desired files will be backup automatically. File abc.xyz will be backup to abc.xyz.zip.

Calculate MD5 checksum for your downloaded files before any bad program touch them!

I guess most people do not like the anti-virus settings of their download software since their anti-virus program is already running in the background. But hey, don’t have these settings lying idle! You can always make use of them to calculate MD5 checksum for your downloaded files.

Configurate download software step by step (I’m using FlashGet as a sample)

1. Open FlashGet, click the Opt.
   
2. Go to the Anti-Virus page
