WhoLockMe can be a very powerful addition to your security arsenal. I was having some trouble with a particularly troublesome colleague of mine who left plenty of data on my desktop which was always being added and deleted without any protection. He used to create a new email address every time he logged onto the net which was always new and had lots of junk in it. Having this software on my computer fixed this problem for me pretty much right away.
Another very powerful piece of software in your arsenal to keep your identity safe is WhoLockMe which is available to download for free. This is a desktop icon in the system tray that loads when you save an important file. It can then be used to lock your computer screen so that nobody can see any other information on it such as the time or date of the document.
A very simple desktop icon that does exactly what its name implies. When you download WhoLockMe, you get the latest version which is v1.2. This download fixes the latest known security flaws in the file browser extension v2. You also get support for the new v3 version which is also free.
