1.

Is FREE CompuSec® compatible with Windows Vista?

Yes, it is compatible with all 32 bit Windows Vista.

2.

Is FREE CompuSec® compatible with Windows XP SP2?

Yes, it is compatible. Users can upgrade to Windows XP SP2 after FREE CompuSec® is installed.

3.

4.

How does FREE CompuSec® work?

FREE CompuSec® intercepts all reads and writes to the hard disk. Just before information is written to the hard disk, Free CompuSec® encrypts it. Conversely, right after any data is read from the hard disk, FREE CompuSec® immediately decrypts it. So the process of encryption and decryption is transparent to the user. Note that first-time encryption takes a longer time than the subsequent encryption and decryption process.

5.

How long does it take to encrypt a 40GB IDE HDD?

Depending on the size and specifications of your hard disk and the mode it encryption. Encryption before booting is much slower than encryption while working. In general, Encryption while working takes about an hour for 10GB.

6.

Which part of my computer does it encrypt?

FREE CompuSec® encrypts your entire hard disk, including all files, directory information, and operating system.

7.

Can FREE CompuSec® encrypt partitions?

No, as FREE CompuSec® encrypts your entire hard disk, including all files, directory information, and operating system.

8.

What algorithm does FREE CompuSec® use?

FREE CompuSec® uses AES 256-bit to encrypt your HDD.

9.

I cannot logon to my OS, I see ‘You have no access to this computer.’ after entering my user ID and password.

This message implies that the wrong user ID has been entered. Please check if you have ‘Caps Lock’ on or that you have typed your user ID wrongly. User ID is case sensitive.

10.

I cannot logon to my OS, I see ‘Invalid logon! Please retry.’ after entering my user ID and password.
This message implies that the wrong user password has been entered. Please check if you have ‘Caps Lock’ on or that you have typed your user password wrongly. User password is case sensitive. If you have just installed FREE CompuSec, do take note that the initial password is "start123".

11

I have entered a password during installation. After the installation is completed and my machine is rebooted, what can’t I use this password?

The password you have entered during installation is the ‘password reset code’. The purpose of this code is to enable users to reset their password when they have forgotten their password or do not have their Backup Security File. To use this option, click on the ‘F1’ keyboard button to activate a Service Menu when the CompuSec® logon screen appears after reboot. Choose option ‘1. Reset password’.

You will need to enter your User ID and click on ‘Enter’ button. Using your User ID prevents this password reset feature from being misused by unauthorized people. You will be prompted to enter your password reset code and the new password you like to use. Your new password may be changed as many times as you wish, but your password reset code is a fixed code you need to determine during installation. It is advisable to use a code you will most likely to remember.

12.

I have forgotten my password, what should I do?

If you forgot your password, you can reset your password using your user ID and the password reset code that you have entered during the installation process. Refer to the instructions given in reply to question 10.

13.

I have completed the installation, successfully changed my password and have logged into the CompuSec logon screen. Why do I see another small ‘gray’ logon screen a few moments later? Can I use the same username and password which I have used earlier at the CompuSec logon screen?

The small ‘gray’ logon screen is for the Single Sign On module of the CompuSec® software. It helps users to login to their Windows automatically. To activate this feature for the first time, you will be asked to enter your Windows User Information such as your Domain, Username and Password. This is not your CompuSec® username and password. The ‘Single Sign On’ screen looks like a normal Windows logon screen but with more features and buttons.  Click on ‘Logon & Save’ to store the information for automatic logon to the operating system. If you do not want CompuSec® to save the login details, please click on the ‘Logon’ button instead. You will be prompted for the same login details each time you access Windows.

14.

When I go to ‘Start > Programs > Security > CompuSec Service’ option, I can create a Security File. What is the use of this file?

With all program installations, we strongly recommend our users to create a Backup Security File for the service recovery function. During installation, users are prompted to create a backup of the ‘SecurityInfo.dat’ file. This file is used when users need to update CompuSec® components or uninstall CompuSec®. You can choose to store this file in a separate device such as a CD or a file folder.

15.

How do I uninstall FREE CompuSec®?

To remove FREE CompuSec® software, please use the de-installation option found in the Service Menu. You can find this Service Menu by clicking on the 'Start' > 'Programs' > 'Security' > 'CompuSec Service' > 'Uninstallation of CompuSec' button. Please ensure that no other applications are running during the uninstallation process. Click ’Continue’ to proceed. If your hard disk is encrypted, please decrypt your hard disk first before uninstalling.

16.

I need to use my PC during the hard disk encryption process. What should I do?

CompuSec® has a background encryption utility that allows user to encrypt the entire hard disk while using the PC. During the installation process, you will be asked to choose the encryption status to activate this utility. At the Service Menu, users must click on ‘Manage HD encryption’ button. Choose the option ‘Encryption while working’ at the drop down menu to enable background encryption while you run applications in the foreground.  This option also enables the encryption or decryption process to be stopped by normal computer shutdown or in hibernation. Click ‘Continue’ to save this option and return to main menu. The process will start at the next computer reboot.


Note:

If ‘Encryption before booting’ and ‘Decryption before booting’ options are chosen, the encryption process cannot be interrupted.

17.

I want to remove FREE CompuSec® from my computer, but I have lost my SecurityInfo.dat file, how should I uninstall?

To uninstall without your SecurityInfo.dat file, go to ‘Start > Programs > Security > CompuSec Service’ menu, click on the ‘Service and Update’ button and select the ‘Backup Security File’ feature. This feature will create your SecurityInfo.dat file and proceed with deinstallation.

18.

Do I need to uninstall the older version of FREE CompuSec® before I install the latest version? What will happen if I do not uninstall?
Yes. FREE CompuSec version 5 has major architecture changes and cannot be upgraded from any version 3 or 4 onwards.

19.

Why does my anti-virus detect FREE CompuSec® software as a virus?
Please let us first assure you that we do not have any viruses in our program and will never intentionally harm our user's computers. We will explain why anti-virus software detects FREE CompuSec® as a virus, essentially due to the mbr.bin and the flp_mbr.bin files. CompuSec® has a pre-boot authentication mechanism that requires a modification of your Master Boot Record (MBR). Your MBR are files that contain important information on how and where your operating system is and other system information.

Therefore, in order to authenticate the user before the operating system boots up, we are required to modify the MBR. Why do we need to do so? Well, as you might probably know, many software (i.e. keylogggers) are able to spy and record keystrokes that are performed when you are using your PC. However, these programs can only run using the windows operating system. Therefore, having an authentication process before your operating system boots up has proven to be a much more secure solution. So why would anti-virus programs pick this up as a virus? Well, very simply, modifying (or rather we should say destroying) your MBR is also the easiest and most efficient way to cause serious damage to a person's computer.

In fact, it is so popular that there is even a category of viruses that does this - they are called boot sector viruses. Boot sector viruses destroy your MBR and cause endless nightmares. Since there are so many variants of boot sector viruses, anti-virus companies are coming up with a Heuristic approach to counter this trend, rather than depend on known signatures or codes of the virus. They now simply try to predict what the virus code is likely to do. And when they see a particular string, though they are not sure, they simply declare it a dangerous file or a virus. Well, anti-virus programs are also known to give false alarms. We believe this is one of them.
