  5. If you think your operating system infected by malicious software, update, and scan using an anti-virus.
  6. After scanning your computer, disable your anti-virus including firewall and VPN that may interrupt the connection.
  7. Then make sure that your ISP is not having any problem. Use a browser and go to Speedtest.net to verify.
