PCLogger is an install and forget utility. It runs as a windows application that sits in your System Tray. Its main function is to monitor key changes in your PC in the background, e.g. what software/application is being installed or changed, changes in specfic PC folders, and changes to important areas of the NT registry. Unlike other software that requires manual scanning to detect what has changed to your PC, PCLogger works in real time.

The main function of PCLogger is to log key changes of your PC. While it does not fix or remove malwares/viruses in your system, the information it captures may help you to identify the what, the when and the where. This capture of information is not only related to changes by viruses or spywares. In fact, any changes by anyone (including yourself) or any applications will be captured. The captured audit trail details may assist you (or someone more PC-savvy) to trace or diagnose when certain changes caused your PC to misbehave. Keeping track of what you have installed may empower you or your support engineer to perform the necessary diagnosis if something did go wrong.

PCLogger subscribes to operating system events thus enabling an immediate detection when the particular event is triggered. One key difference to this type of monitoring programs (e.g. your AntiVirus program) is that PCLogger does not need a virus definiton file. It works on the analogy that if a thief is breaking into your house, he must enter your house through a predefined opening (i.e. a door, a window or the roof). It does not need to know who the thief is and what is his name, his height and how he works. By monitoring predefined locations, PCLogger is designed to be future proof (of future virus or other malware).

Your children have just installed an internet game that they have downloaded. Immediately, PCLogger alerts you that another new file (c:\windows\fntldr.exe) was created. With a bit of investigation, you would have found out that the program is actually a hijacker and proceed to remove the intruder; thus saving you hours of grief trying to figure out why every time you start up your internet browser, you are brought to another web site.

You received an email enticing you to visit a certain web page. When you visit the web page, you see an empty page. That is when the fun starts when PCLogger started to alert you! PCLogger will detect that a file "msxmidi.exe" is created in your windows directory. Huh? Something definitely is happening behind your back. A search on the net will reveal that you have a keyboard logger attempting to capture your password when you logon to your favourite bank (Westpac or ANZ). Who knows, this may save you $$.

You are about to send your PC out to be repaired. Before you send your PC, you take a snapshot of all your drives. When your PC is returned, you take another snapshot of all your drives. By comparing the snapshots (using Windiff e.g.), you know exactly whether your drives have been tampered or not; thus giving to you the peace of mind that you required.

You found your browser suddenly became very slow. You also noted that you cannot open a popup window. Ok... You have left your son playing on your PC the last few days (perhaps, your son has downloaded a virus). So, you checked your PCLogger and you immediately confirmed that there is a new BHO installed 2 days ago around the same time when your son installed MessengerPlus.exe. The BHO is named "req.dat". When you searched the net, you found that you have caught a keyboard trojan on your PC! After removal of the trojan, you quickly checked your internet bank account details to see if there is any misappropriate transaction. Lucky you, the keyboard logger has not hit your account yet. With this discovery (that you did have a keyboard trojan in your PC), you take the decision to change your online banking password and your PC password immediately for a peace of mind.
