Here we are going to discover How to Find Viruses Using Netstat ? This is just a simple trick that you can find viruses in your computer. This trick was provided by cobija & hackyer and KN.I mentioned steps Bellow to Find Viruses Using Netstat.
PART 1 - Preparing Task Manager Step 1: Open Task Manager (ctrl+alt+del). Go to the processes column and click View > Select Columns
Step 2: Check the top one (PID (Process Identifier))
Step 3: Now, organize Task Manager by PID. This will make things easier to read for the next step.
PART 2 - Using Netstat to see Established Connections Step 1: Now you want to go into Start > Run > cmd > "netstat -ano". It should look similar to the picture below:

Only look for
ESTABLISHED connections (it would be established if its a RAT or malicious), read the PID and crosscheck into Task Manager. Notice in my example that the only established connections use the PID 424. Lets take a look at what that is:
As we can see, its Firefox. Now lets say you notice the PID reads something like "svchost.exe". You should open the file location by right clicking it and pressing Open File Location and either scan it with Virustotal or check to see if in its legit location (if it was in Appdata or Program Files and it is svchost.exe, then you may have a problem).
