"Port scan blocked" Notification. What Is It? (2024)

There are a few ways to know why a hacker targeted you and whether there are vulnerable ports on your machine.

1) Look for unusual activity.If you've noticed any unusual activity on your computer, such as pop-up ads, slow performance, or unexpected programs, then it's possible that you've been hacked.

2)Scan your computer for malware.There are a number of free and paid tools that you can use to scan your computer for malware. If you find any malware, then you'll need to remove it immediately.

3) Check your firewall settings.Make sure that your firewall is enabled and that it's blocking all incoming connections that you don't recognize.

4) Look for open ports (search for port scanner on google to check for open ports).You can use a port scanner to see if there are any open ports on your machine. If there are, then it's possible that these ports are vulnerable to attack.

Here are some additional tips to help you protect your computer from hackers:

1) Keep your software up to date. Software updates often include security patches that can help to protect your computer from known vulnerabilities.

2) Use strong passwords. Your passwords should be at least 12 characters long and should include a mix of uppercase and lowercase letters, numbers, and symbols.

3) Be careful about what websites you visit and what files you download. Only visit websites that you trust and only download files from reputable sources.

4) Use a firewall and antivirus software. A firewall can help to block unauthorized access to your computer, and antivirus software can help to detect and remove malware.

By following these tips, you can help to protect your computer from hackers and keep your data safe.
