Is it safe to open batch file? Or not?

Before this Post, you have learned about batch files in previous tutorials. There are showed that batch files are safe. But really is it? Because some malicious peoples destroy PC using batch files. Because most of the antivirus didn't scan batch file properly or skip scanning batch file. But how a simple batch file destroys a PC? Sometimes batch files download unwanted files from the internet without user permission and run the program in the background (The program compressed into an archive file so the program hides its code in it) and it destroyed pc by slowly or too fast that user can't do anything after that. So let us see how to verify that the batch file is safe or not.

1. Use VirusTotal

virustotal virus scanner (

VirusToal is a website where you can scan your file for free. Just upload the file into VirusTotal Server and wait a few times to view the report. Sometimes VirusTotal antiviruses detect the batch file as a virus and sometimes not because most of the Antivirus Publishers thought that, A Simple batch file can't harm any PC, but it is not real. The batch file can damage the PC like an exe virus.

2. Enable UAC

What the combination between batch file and UAC? We know that UAC alerts you when we install any program into Computer. While installing, Programs copies its files into System folders (such as System32) and overwrite files or delete system files. So UAC Alerts you when you will changing into a system file. If you turn on UAC at maximum level, then If any batch file requests Administrator Permission then you can prevent it to change system files. But it can modify user-created files from the desktop or Documents folder (Like a Ransome Virus). And more Safe Option is that lock UAC means You also wouldn't disable UAC.

How to Enable UAC?
Go to 'Control Panel' and Search for 'UAC' then Click on 'User Account Control' then Type your Administrator Password and Press 'Yes' button and Set the Switch to 'Always Notify' and Hit the OK button. You may need to manually type your password again.

How to lock UAC?

Click on Advanced and then click on 'Add'. Type 'everyone' in the box and hit the OK button. Set 'Apply to' as 'This key only' and Set Permissions like the below box.

3. Use Antivirus

Antiviruses are awesome. They detect malicious programs into your PC and protects you by his (or her, If the antivirus made by a female programmer lol) Real-Time Protection. Also, sometimes Antiviruses detects batch files. For this feature, you need to use up-to-date Antivirus (like Emisoft). Most Antiviruses detected malicious batch files using 'Behavior Sheild', It checks every program behavior and if it did something wrong then Antivirus sent it into Virus Chest or Delete it permanently.
