How to Delete Viruses Manually?

 Previously I've described Unlocker,Virustotal.com, and how to view hidden folders.At present these are the tools needed to manually delete viruses.
 1.Start off by viewing the target drive using a file manager.
 2.Most viruses are stored in hidden folders;these can be easily viewed in a file manager.
 3.Next browse for files that are not user created;especially ones with suspicious names including autorun.inf files.
 4.However some folders like the system volume information folder and others are system data;dont delete them unless you know what you're doing.
 5.Then delete the file;in case a message "unable to delete,file is in use" or something similar is displayed use unlocker to unlock the file.
 6.Now in case of doubt use the virustotal service to get a broader opinion.
  In my next post I'll describe my experience when I tried this on my usb drive.
