One way of prevention so that we are not attacked by computer viruses is to prevent the execution of the virus file. One way is to prevent transmission of the virus from flash. For prevention, we can use one of the features available in Windows XP that is Local Security Settings.
The way it works is to protect the computer from the execution of all *. exe files. So that when we open the files in the flash and unbeknownst to us was to run a virus file, then the execution process will be in the protection or are canceled.
The steps are
->
1. Select Start>> Control Panel
2. Select Administrative Tools>> Local Security Policy
3. Select Software Restriction Policies>> Additional Rules
4. Right-click on Additional Rules>> select New Path Rule ...
5. In the Path column, select Browes flshdisk select which drive is located, eg in I: \
