  • System slowdowns: Performance degradation, delays in processing, or unresponsiveness.
  • Unexpected pop-ups: Display of unsolicited advertisements or alerts.
  • Disabled security software: Trojan.Agent may attempt to disable antivirus or firewall protection.
  • Strange system behavior: Unusual processes running in the background or unauthorized access to files and folders.

Sources of the infection

  • Malicious downloads: Trojan.Agent often spreads through infected files or software downloaded from untrustworthy sources.
  • Phishing emails: Opening malicious email attachments or clicking on malicious links in emails can lead to Trojan.Agent infections.
  • Drive-by downloads: Visiting compromised websites that exploit vulnerabilities to deliver malware to your system.
  • Infected external devices: Transmission through infected USB drives, external hard disks, or other removable media.
  • Exploiting software vulnerabilities: Trojan.Agent may take advantage of unpatched software or operating system vulnerabilities.
