A Trojan Virus or Trojan Horse virus is a type of malware that impersonates legitimate files or programs for conceding its true contents. The payload hidden in the Trojan Virus remains unknown to the target user and can act as delivery vehicle for a variety of threats. Unlike normal viruses, a Trojan virus is capable of replicating itself.
Types Of Trojan Virus
Common types of Trojan Virus are:
- Backdoor Trojans – This type of Trojan Virus allows hackers to remotely access and control a computer for uploading, downloading, or executing files.
- Exploit Trojans –These Trojans inject a machine with code that is specifically designed to take advantage of vulnerability inherent to a specific piece of software.
- Rootkit Trojans –These Trojans prevent the discovery of malware already infecting a system so that it can cause maximum damage.
- Banker Trojans –This type of Trojan Virus specifically targets personal information used for banking and other online transactions.
- Distributed Denial of Service (DDoS) Trojans – These Trojans are programmed to execute DDoS attacks, where a network or machine is disabled by a flood of requests originating from different sources.
- Downloader Trojans –These are files written to download additional malware, often including more Trojans, onto an infected system.
Detecting A Trojan Virus:
Some common telltale signs of infection by a Trojan Virus are:
- Poor Device Performance
- Strange Device Behavior
- Pop-Up & Spam Interruptions
If the system exhibits any of these behaviors, it is possible that system is infected with a Trojan Virus. Here are some ways to detect the Trojan:
- Search the system for programs or applications you don’t remember installing.
- If you find any unrecognized file names, search online for these file names to check if they are recognized Trojans
- Scan the system with antivirus and antimalware software to see if it detects a malicious file.
Defending Against Trojan Virus
As preventive measures, stick to following practices to defend your system against Trojan Virus:
- Install an effective internet security solution
- Refrain from downloading or installing software from a source you don’t trust
- Never open an attachment or run a program sent in an email from an unrecognized address
- Keep all software on your computer up to date with the latest patches for avoiding vulnerabilities
- Make sure a Trojan antivirus is installed and running on your system
- Run regular system scans
