Develop good security habits, such as not opening suspicious emails or websites; close or delete unnecessary services in the system; many viruses spread through vulnerabilities, so it's essential to timely patch the system; install professional antivirus software for real-time monitoring, and ensure that the real-time monitoring function is enabled while surfing the internet.
My Suggestions:
1. Install professional antivirus software, upgrade it to the latest version, and enable the real-time monitoring program.
2. Install personal firewall software with a "Trojan Wall" function to prevent password loss.
3. Enable the real-time monitoring of the firewall and antivirus software while surfing the Internet.
4. Do not browse junk websites.
5. Regularly apply system patches to prevent potential problems.
6. Perform virus scans in a timely manner, preferably once a week.
7. Scan downloaded files for viruses before opening them.
