Viruses on Windows XP

My dormmates ask me from time to time about unusual things that happen with their Microsoft Windows XP systems. Because I am usually short on time, I seldom bother to search the Internet to find out what specific virus has infected a computer, and to look for specific fixes from Microsoft itself or from respectable anti-virus companies. In most cases, I just do the following, and oftentimes, the problem is fixed.

  1. Run Task Manager.
  2. Terminate the Explorer process. Explorer is the manager of the graphical interface of Windows. A large number of viruses inject instructions into this to recreate them if they are deleted, or to start the processes needed by the viruses again if the processes are terminated.
  3. Terminate suspicious and non-critical processes.
  4. Run msconfig.
  5. Make sure that Selective Startup is selected. In the Processes tab, a list of processes run upon boot up is shown. Only processes wished to be run upon boot up should be ticked.
  6. Reboot.

Some cases I’ve encountered required manual deletion of certain files after these are done. Others required uninstallation of malware. There were also a couple that required the restoration of one or two original Windows system files. Also, there are times when the Windows systems seem too corrupted that I just end up recommending reinstallation of the operating system.

Of course, I never forget to remind people to install security patches from Microsoft whenever new ones become available, and although I hated having an anti-virus software running on my Windows system before, I always tell my dormmates to install one if they don’t have any installed yet, and to update their virus definitions regularly. Preventive measures ought to help.
