Kaspersky Anti-Virus 2010

Sometimes after removal of F-Secure anti-virus software with the standard means and the computer restart some records may still remain in the system registry and prevent a Kaspersky Lab 2010 product from installation.

Thus, it is very important to remove F-Secure before installation of a Kaspersky Lab 2010 product.

Before the files are copied onto a hard disk the Setup Wizard scans the disk for software incompatible with Kaspersky Lab applications. Records in the system registry are recognized by the Setup Wizard as fully installed F-Secure software, even though the product was removed and is no longer installed on the PC. As a result Kaspersky Lab Setup Wizard asks to delete the detected incompatible software manually and terminates the installation process.

How to uninstall F-Secure anti-virus using standard Microsoft Windows tools:

• in the bottom left corner click the Start button
• perform the following actions:
• for Windows XP:
• select the Control Panel item

• in the Control Panel window click Add or Remove programs

• for Windows Vista and Windows 7:
• select the Control Panel item

• in the Control Panel window click Programs

• in the Programs window select Programs and components

• in the list of programs select the F-Secure anti-virus
• perform the following actions:
• for Windows XP:

• for Windows Vista and Windows 7:
• double-click the application name
• in the Programs and Features window click the Yes button
• in the Setup Wizard, select the Delete all option
• in the Setup Wizard, click the Start button. Wait until F-Secure is uninstalled
• if the uninstallation process is successfully completed, you will be asked to restart your computer
• in the Setup Wizard, select the option Restart now (recommended)
• click the Done button

Try to install your Kaspersky Lab 2010 product once again.

As a result F-Secure anti-virus will be removed from your computer. If F-Secure anti-virus has been successfully removed from your computer you do not need to perform the following steps. If an error message informs that F-Secure anti-virus removal was unsuccessful you will have to delete F-Secure anti-virus using a special utility.

Special utility Uninstallation Tool.exe to uninstall F-Secure software

In order to remove F-Secure software, you can use a special utility Uninstallation Tool.exe (UNINSTALLATION TOOL (C) F-Secure Corporation. Distributed under the terms of the F-Secure License Terms).

In order to remove the software, perform the following actions:

• download the Uninstallation Tool.exe file. The uninstallation tool does not delete F-Secure products installed in the folders С:\Windows, С:\Documents and Settings, C:\Program Files
• carefully read the readme.txt file before running the uninstallation tool

• run the UninstallationTool.exe file by double-clicking it
• in the F-Secure Uninstallation Tool 3.0 - InstallShield Wizard window select I accept the terms in the license agreement
• click the Next button
• wait until the process is completed

• this will clear the directory in which the F-Secure's software was installed. After the uninstallation process your computer will be restarted.

Try to install your Kaspersky Lab 2010 product once again.
