Virus killing quick guide

Here is some advice to remove viruses and trojans that get inside your customer’s PC.

1. Kill the invader. Task Manager is almost always blocked by the virus, so use the command line instead:

   tasklist
   taskkill /f /pid 892

2. Restart in Safe Mode (F8 key at Windows boot). If you plan to install an antivirus in the next step, choose «Safe Mode with Networking».
3. Install an antivirus if you can, for example Microsoft Security Essentials, and run a full scan.
4. Clean the Startup folder for the user and under «All Users».
5. Clean the registry with Regedit, knowing what you are doing, in keys like:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
   HKEY_USERS\S-1-5-21-...-1000\Software\Microsoft\Windows\CurrentVersion\Run

After some cycles like these, quite often every bug is killed. Good hunt!
