Additionally, you can also perform manual scans by checking running processes and services, browser extensions, and installed programs.

    Pro Tip: Avoid using any untrusted devices such as USBs, as they can also have viruses and malware that can infect your system.

    Ensuring Effective Trojan Virus Protection

    The best way to protect your system from Trojan viruses is to install reliable antivirus software and keep it updated. You can also enable your firewall to block unauthorized access to your computer. Additionally, practice safe browsing habits and avoid downloading from unknown sources.

    Pro Tip: Create strong passwords and change them every three months to prevent unauthorized access to your system.
