4S Lock provides additional level of protection from unauthorized access to PC.

4S Lock 1.07 enables you to lock your workstation at any time by simple double click on system tray icon. Transparent lock is available. 4S Lock also provides startup/logon computer lockdown. During computer startup 4S Lock seamlessly replaces standard windows shell, and switches it back having a password. With version 1.07, 4S Lock also automates computer cleanup. Such files as temporary internet files, cookies, internet history, recent documents traces and other files reflecting your working and internet browsing habits are automatically and permanently destroyed upon computer startup or shutdown. Normally, 4S Lock makes an auto show of top world cars and sport utilities. 10+ pre-configured image sets are available for free one-click download within the program interface. With Synaptex MyScreenSaver Builder 1.1 you can easily package your own images into a single file (MSS-file) and use them with 4S Lock.
