But those who dont have HPD enough to buy a new IP? Or got a virii installed just before going offline?
You could always install your own virii on your gateway and make it inoperable to others short of remote disinfect. That way when you come back you have some spare HPD as the virus works for you and others will have a hard time remote disinfecting.
If you got a nasty virus just before vacation, have a friend remote-disinfect you or if you have Gold, backup your data on the Secure FTP and Format HDD with IP change.
