Ever download something new? And your so excited about it, and you just run the setup.exe, or the program itself? Realizing afterward, that you didn't check it first with novirusthanks.org?
Well here's a few things to do:
--Open up Task Manager,
--Click the "Processes" tab
--Then "View" > "Select Columns"
--Then click the box that says PID (Process Identifier)
--Now click start, run, and type "CMD"
--Then type "netstat -b"
(Shows the active connections with there PID)
--Then type "netstat -an |find /i "listening"
(Shows open Ports, look for a matching port from the two commands, and take note of the process)
An Example would be as follows: netstat -b command
----------------------------------------------------------------------
Active Connections
Proto Local Address Foreign Address State PID
TCP xpwindows7:PORT Localhost:PORT Established 2560
[firefox.exe]
----------------------------------------------------------------------
An Example Of:
netstat -an |find /i "listening"
----------------------------------------------------------------------
C:\Documents and Settings\User>netstat -an |find /i "listening"
TCP x.x.x.x:PORT x.x.x.x:PORT Listening
TCP x.x.x.x:PORT x.x.x.x:PORT Listening
TCP x.x.x.x:PORT x.x.x.x:PORT Listening
TCP x.x.x.x:PORT x.x.x.x:PORT Listening
----------------------------------------------------------------------
These Commands tell you in the most basic form if you have an unidentified process connecting to a foreign address.
If you notice that something IS connecting out, take note of the process, Foreign Address, and PID. Match the PID with the PID under Task Manager, and end that process.
You can also manually look for it in start up. This is where most Viruses like to hide.
Step 1
-------
What your going to do in these next steps, is look for that process that you noticed was "Abnormal" or connecting out.
Click Start, RUN, and type regedit. There are Two places you can check for that specific process.
Here--
HKLM\Software\Microsoft\Windows\Current version\Run
Look on the right side, for the process you identified earlier, as UNKNOWN. If you do not
find it there, check,
Here--
HKCU\Software\Microsoft\Windows\Current Version\Run
If you still dont find it, Click Start, Run, Type msconfig, and click the START UP tab.
Scroll down the list of items, and look for the process. If you find it Uncheck the box and apply.
Once you delete it from start up, i would recommend scanning your computer with MalwareBytes or SUPERAntiSpyware. This will clean up any and all remaining files that were associated with the virus.
