What is Trojan:Script/Downloader!MSR

Trojan:Script/Downloader!MSR is a type of malicious script designed to download and install additional malware onto a compromised system. This Trojan typically infiltrates a computer through deceptive methods such as phishing emails, malicious websites, or bundled software downloads. Once executed, it connects to remote servers to fetch and execute further malicious payloads, which can range from ransomware to data-stealing malware. This Trojan is particularly dangerous because it acts as a gateway for various types of threats, making the infected system more vulnerable to subsequent attacks. Users may notice unusual system behavior, such as frequent pop-up ads, slow performance, or unauthorized changes to system settings. Detection and removal can be challenging as the Trojan often disguises itself and may disable antivirus software. Immediate action, such as running specialized malware removal tools and keeping all software up-to-date, is crucial to mitigate the risks associated with this threat.
