As mentioned by others, I would have to think anti virus and firewall protection and operating system security updates are the primary rule of thumb for protecting against malicious access to our home computer, or any other personal information in that case, as Kasey C. of San Francisco, CA advised. However, when typing in passwords or accessing accounts or websites online, any program designed to invade and steal such information only needs a second or two at the right time to hijack said information. All too often, you're a bit late on finding out that such a situation has occurred, and have to suffer a system clean and virus check. Most sites have encryption for protecting your password as far as storage at their end, but if stored in a cookie on your end, it leaves it open to malicious programs other than what your own security walls and protection programs try to protect and defend. More often than not, identity theft of passwords is due to your own home computer being invaded, unless a company has a major hack break in that you have seen rarely or on a more uncommon note, on the news. Storing your passwords on your home computer, then selecting ''do not remember me'' or NOT choosing ''remember my password'' on each specific web site is 'probably' the best thing one can do for not allowing a password the ability to 'float around' online. I merely keep my information in a file in a notepad format, creating said file in SAFE MODE, then I use a program such as 'PDL Hider' ( a file and folder privacy converter ) to alter my files over to a slightly more secure format. A home user can then simply place them in a better location on their computer, ''off station'' of the normal operating system hard drive ( I use two hard drives on my home computer ), or one can store them on a partitioned area of your drive ( even using an external 'ThumbDrive' can be practical ). This way I can feel a bit more secure in not having important files on the main operating system hard drive which may get viewed, monitored or 'violated'. Further, in that I'm not going to try and make this sound as if I'm promoting certain products or brand names, I take a couple of extra steps to feel a bit more safe, and simply put to use additional security programs. So just for an example and using my own personal experience here at home, I've found that a program such as ''Security Task Manager'' in my own case, helps a lot. It?s a system process analyzer, but here for our main point, it includes a sub-program called ''Spy Protector'' which allows the user to select modes where you can prevent keyboard monitoring and other program monitoring such as macros (user activities) mouse activities, starting and ending or use of personal programs, and keyboard inputs (internal messages). This prevents other users if the case, or malicious programs, from accidentally or otherwise malevolently accessing your private info. Activating blocks at these points of access will disable any monitoring of your input to sites from your end. When you need that information to use on a site, simply unlock your concealed password and information file with the .pdl type converter, then as a further safety measure, never 'type in' your information, simply copying and pasting the required field in to complete any information. This is saved to your clipboard at the time of course, but is blocked from being monitored at the time. For later, an easy to use cleaner program such as ?WindowWasher? in my case and its frequent use is 'always' a smart recommendation for normal system cleanup, and washes any all information from that end, including storage cookies. I may have a loophole or two on that process line and way of thinking so feel free to correct me if you wish, as I can take polite corrective criticism most of the time *smiles*. Hope some of this helps. Drew
