1. Install an antivirus program: Install an up-to-date, reputable antivirus program and make sure it is correctly configured to update automatically and to run regular scans.
2. Use firewalls: Firewalls help block malicious software from entering your computer or network and can alert you to suspicious activity.
3. Keep your operating system and other software updated: Installing the latest updates for your operating system as well as any other software, such as web browsers and media players, will help protect you against new threats.
4. Use caution when opening emails and downloading files: Exercise caution when opening email attachments or clicking on links in emails, even if they appear to come from a trusted sender. Likewise, be careful when downloading files from the Internet.
5. Be wary of suspicious websites: Be aware of the websites you visit. Malicious websites may try to install malware on your computer without your knowledge.
6. Monitor your PC’s performance: Regularly monitor your system for possible signs of infection, such as slow performance, error messages, or sudden changes in your home page.
