Protect your system from Hackers by closing open ports and remote connections on your computer
Is your system being monitored or controlled by somebody else in your absence?
Here you can find the answer.
If I want to enter in your house mutely, i need to find out open doors or windows in your house which you left open because you were unaware of the existence of that door or forgot to close that door.
In the same way our computers also has doors called PORT which it uses to connect to other computer to access service like websites, torrents download,software update services, remote connection, etc. If we are accessing any kind of service or application that uses network connection, a PORT is used for every service and application.
Here is the list of common ports and associated services:
- 20/21: File Transfer Protocol(FTP)
- 22: Secure Shell(SSH)
- 23:Telnet
- 25: Simple Mail Transfer Protocol(SMTP)
- 53: Domain Name System(DNS)
- 80: Hyper Text Transfer Protocol(HTTP)
- 110: Post Office Protocol(POP)
- 143: Internet Message Access Protocol(IMAP)
- 169: Simple Network Management Protocol(SNMP)
- 443: Hyper Text Transfer Protocol Secure(HTTPS)
Lets begin:
- Open Command Prompt
- Type command -> netstat -ano
- It will show all connections on your computer and all open ports.
- Proto is protocol used for connection, Established state means connected, Listening means ready to connect to other system.
- Now note down the PID of established connection.
- Open new command prompt window and type tasklist
- Now check that PID in this list, to find which application has created that process like svchost.exe, winlogon.exe, explorer.exe, iexplore.exe, etc
- Now if you find unknown service running or service with unusual name, it may be malware, but make sure it is not a system process by searching the name at Google.
- Now type command taskkil /PID 816 /f //at place of 816 use your PID
- Job done, yove have closed the port and connection.
Always use Activated and Updated antivirus installed on your system. Avast Internet Security or Quick Heal Total Security package are my favorites.
