How to remove Trojan:BAT/PSRunner.VS!MSR

What is Trojan:BAT/PSRunner.VS!MSR

Trojan:BAT/PSRunner.VS!MSR is a malicious script-based Trojan that primarily uses Windows PowerShell to execute harmful commands on a compromised system. This type of malware is often delivered through phishing emails or malicious attachments that, when opened, initiate the PowerShell script. Once active, it can download and execute additional malware, steal sensitive information, or create backdoors for further exploitation. The Trojan’s reliance on PowerShell makes it particularly stealthy, as it can blend in with legitimate administrative tasks. Detecting and removing this threat requires advanced tools like FRST (Farbar Recovery Scan Tool) and thorough system scans. Users should always be wary of unsolicited emails and attachments to prevent initial infection. Regularly updating software and maintaining robust cybersecurity practices can help mitigate risks associated with such threats.

How Trojan:BAT/PSRunner.VS!MSR infected your system

Trojan:BAT/PSRunner.VS!MSR primarily infects computers through malicious email attachments, compromised websites, or infected software downloads. Once a user unknowingly executes the infected file, the trojan deploys a PowerShell script that downloads and runs additional malicious payloads. This script often exploits vulnerabilities in the system or installed applications to escalate privileges and achieve persistence. The trojan can disable security software, modify system settings, and create backdoors for remote attackers to further compromise the system. Users are advised to keep their software updated, avoid opening suspicious email attachments, and employ robust antivirus solutions to mitigate the risk of infection.
