Traces of your internet browsing trails are left behind whenever you surf the web on your Windows PC. This can include website addresses, text phrases entered into search bars (such as Google and MSN), cookies, images that have been loaded into your browser, and more. It can become quite a liability if people don't know about this and unsuspecting family members stumble across personal information.
It doesn't mean you're surfing bad sites if you want to keep your internet browsing history to yourself. You could be looking up medical info about something you'd much rather keep private. Christmas shopping is another reason you might want privacy.
Another consideration when it comes to Windows retaining all this data in cache and history folders is that your privacy is at stake in case your computer becomes infected with a malware program. Most people don't want any data collected about them, even if it's just for an anonymous web advertising tracker.
Oftentimes you'll hear about people who discover family members and loved ones doing unsavory things on the internet, and often it's because they uknowingly came across internet addresses saved in the URL bar.
In order to thoroughly clean out your computer we recommend using a privacy software tool such as ParetoLogic Privacy Controls.
Your browser will most likely have a "clear private data" option that's usually available under the Tools menu. Both Internet Explorer and Firefox have this option. However, this is not a complete solution. Your search history is often not fully cleaned out and images might be left in the cache.
In the event that you want to make sure you do a completely thorough job of clearing your computer of all trails then you should definitely consider one of the several good privacy software programs available. Acrobat Reader and Macromedia Flash are third party programs that store web and browsing data, and these tools will give you the option of cleaning them out as well.
