There are several ways to view open ports. It should be noted that some open ports can be a potential threat to the operating system, and if such a port is actually identified, the problem needs to be corrected urgently.
Instructions
Step 1
First of all, you should take into account right away that an open and potentially dangerous port in the system most likely indicates that the computer has a very ineffective protection tool. If the Internet is constantly used, then it is simply necessary to ensure the security of the operating system. To do this, you need to install an effective antivirus (for example, Kaspersky Internet Security). Quite often, instead of good protection, small free applications are used, which, unfortunately, cannot provide complete security for the system.
Step 2
The easiest way to view ports is with an online check. In order to do it, just follow the link https://2ip.ru/port-scaner and then wait for the results. If during the check a potential danger is found (LISTEN in red), then you should write down the information about the port separately in a notebook, as it needs to be urgently corrected
Step 3
You can quickly fix the problem with a small utility that does not require installation. It is called Windows Worms Doors Cleaner with only one function: closing potentially dangerous ports. You can download the application here https://2ip.ru/download/wwdc.exe. Once the scanner port. Then you need to restart your computer. It should also be noted that this does not prevent the occurrence of such a problem again, this action is performed to ensure security, so to speak, hastily, but in the future it is necessary to install additional and more effective protection
Step 4
After closing a potentially dangerous port, you need to thoroughly scan your computer using security software. If you don't want to spend money on protecting your computer, you can use the free CureIt application or the one-time Kaspersky Virus Removal Tool. It is also advisable to install a firewall (eg Comodo Internet Security).
