Every two months I run a white-space Gutman washer. I delete all my files the same way. I use that same method for all temp files. My internet runs via proxy. I encrypt all my files using a 2056k file encryption program. What else can I do? It does not seem like enough?
If you’re worried about people hacking into your computer to see/steal your files you should have a software & hardware firewall. You should also be running regular Virus and spyware scans, two major ways people can get into your system.
You can keep all of your ‘sensitive’ files on a external harddrive that you only plug in when you are using it.
Have up-to-date anti-spyware and anti-virus protection, and also have your firewall turned on.
