What is Malicious Code | Total Security

Malicious code is a dangerous computer code or web script that creates vulnerabilities that can lead to backdoors, security breaches, information and data theft, and other potential damage to computer files and systems. This type of threat cannot always be blocked by simple antivirus software. Not all antivirus protection is effective in dealing with specific infections caused by certain malicious code, which should not be confused with malware. The term “malware” is reserved for software, while the notion of “malicious code” includes scripts from websites that exploit vulnerabilities to load malicious programs.

Malicious code is a self-executing application that can self-activate and come in various forms (Java applets, ActiveX commands, auto-transmitted content, plug-ins, scripting or other programming languages, etc.) to enrich web pages and e-mails.

This code then offers cybercriminals unauthorized remote access to the attacked system. This backdoor then exposes the confidential data of the infected company. With this access, cybercriminals can erase data from a computer or even install spyware. Even the highest levels of an administration can be affected by such threats. The US Government Accountability Office, for example, has previously been warned that malicious code threatens US national security.

Scripts, worms, and viruses can damage your computer by detecting entry points leading to your most valuable data. Visiting infected websites and suspicious email links or attachments are two major entry points through which malicious code can enter your system. Antivirus software that includes automatic updates, malicious code removal features, secure web browsing, and detection of all types of infections is the best defense.

How Can I Protect My Network From Malicious Code?

Typically, businesses focus on preventative tools to stop violations. By securing the perimeter, businesses assume that they are secure. However, some advanced malicious code will eventually find its way into your network. It is therefore essential to deploy technologies that continuously monitor and detect malicious code that has escaped perimeter defenses. Advanced malicious code protection requires multiple layers of protection as well as high-level network visibility and intelligence.

1. Use antivirus software

Antivirus software can be effective in combating basic, “untargeted” malicious code that could be used by criminals against hundreds or even thousands of targets. Install advanced antivirus protection like a total security

2. Beware of suspicious attachments

The best way to get infected with targeted malicious code is first of all to avoid opening suspicious documents and installing the malicious code. People with better technical and IT knowledge will have better instincts as to what might and might not be malicious code, but well-targeted attacks can be very convincing.

3. Update software

Another thing you can do to protect yourself against malicious code is to make sure that you are always using the latest version of your software and that you download the latest security patches.

What Should I Do if I Find Malicious Code on My Computer? 

If you find a malicious program on your computer, disconnect it from the Internet and stop using it immediately.

Every keystroke could be sent to an attacker. You might want to take your computer to a security expert who could find out more details about the malware. If you have found the malicious code, removing it does not ensure the safety of your computer. Some malicious programs give the attacker the ability to execute arbitrary code on the infected computer. Moreover, there is no guarantee that the attacker did not install other malicious code while checking your machine.

You may want to reinstall your computer's operating system in order to remove the malicious code. This will remove most malicious code, but some particularly sophisticated malware might persist. If you know roughly when your computer was infected, you might be able to reinstall files from before that date. Reinstalling files after the date of infection could re-infect your computer.
