Kaspersky Anti-Virus 2012

Sometimes after removal of McAfee 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 product from installation.

That is why it is so important to fully uninstall McAfee software before installation of Kaspersky Lab’s software.

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 McAfee 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.

In order to fully uninstall McAfee software and its records from the system registry, please follow the recommendations below:

• Uninstalling using standard means of Microsoft Windows.
• Uninstalling using a special tool.

Resolution 1. Uninstalling McAfee products using standard Microsoft Windows tools

1. In the bottom left corner click the Start button.
2. 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

3. In the list of programs select the McAfee anti-virus.
4. Perform the following actions:
• for Windows XP
• click the button Change/Remove (if you are offered to remove some common files click the button Yes, for all)
• for Windows Vista and Windows 7
• double-click the application name
• in the Programs and components window click the Yes button
5. The process of deleting McAfee anti-virus from your computer. In case of successful uninstallation of McAfee anti-virus from your computer, there is no need to perform the following steps. If a message appears informing about errors or informing that uninstallation of McAfee anti-virus was not successful, you will have to uninstall McAfee anti-virus manually.

Try to install your Kaspersky Lab product once again.
