By checking and updating your DNS Server settings, you can prevent internet blockage and ensure your computer is protected from viruses like the infamous ILOVEYOU or Love Bug virus. Don’t forget to keep your antivirus software, like Norton Antivirus, up-to-date to stay protected.
Checking the Operating System Hosts File to Prevent Internet Blockage
To prevent a computer virus from blocking internet access, it’s important to check the Operating System Hosts File. This file contains a list of website URLs and their corresponding IP addresses. To access the file: open the Command Prompt or Terminal and type “notepad %systemroot%\system32\drivers\etc\hosts” (without the quotes) and hit enter. This will open the hosts file in Notepad.
Check the file for any suspicious entries that may be blocking internet access. If you find any, delete them and save the file. This will allow you to access the blocked websites.
It’s also important to keep your anti-virus software up-to-date and avoid downloading suspicious attachments or clicking on unknown links. Be cautious when opening emails from unknown senders or with suspicious subject lines.
By taking these steps, you can prevent computer viruses such as the iloveyou virus, de guzman, love bug virus, and i love you virus from blocking internet access.
