- 1). Update your current virus scanner to the newest virus definitions if you have a virus scanner installed.
- 2). Download and install scanning programs such s AVG, Avast or Malwarebytes to supplement your current virus scanner. While you should not run two virus scanners at once, each program may be able to detect something different.
- 3). Update the downloaded virus scanner definitions to the newest version. This is usually a part of the installation process, but you should always check to ensure you have an updated program.
- 4). Unplug your computer's network cable or shut off the wireless adapter once you have downloaded and updated the programs. If the backdoor is downloading new viruses and allowing another user to control your computer, disconnecting it from the Internet will prevent changes to your system while scanning for threats.
- 5). Run a fast scan for viruses on your computer using one of the virus scanning programs. This will remove the viruses that are easiest to find first and reduce the chance of an interruption during a longer scan. You will need to reboot your computer once the scan has completed.
- 6). Run a second fast scan using a different virus program and remove any threats that it might find. Reboot once this has completed.
- 7). Run a full computer scan using your main virus scanning software. This will provide a more comprehensive scan for any viruses or backdoors installed on your computer. This may take some time and require a reboot at the end.
- 8). Plug your network cable back into your computer once you have scanned and removed all threats.
