On my desktop computer I write documents that I don't want hackers to get their hands on. The documents are password protected and stored on an external harddrive. I turn the external harddrive out from the computer while I go online. Is this good enough protection of my documents?
It also never hurts to encrypt some of those files (especially more sensitive ones). Give AxCrypt (free, light-weight, strong encryption, accessible from context menu) a try.
