（１）Extract (open) the file that you downloaded.

　　Extract the files downloaded as described in (2).6 to (2).9 in the "F-Secure Anti-virus Client Security Quick Installation Guide (Version 8.xx)". The extracted folder wincli-8.xx includes two files:

• READ ME FIRST.txt (this file)
• kuic_fsavcs8.**.msi (F-Seccure 8.** )

　　Note that the uninstall tools that came with Version 7.xx, which are listed below,  are not included.

• UninstallationTool3.exe(F-Secure uninstall tool for Ver 7.0 or later)
• UNINSTALLATION_TOOL.exe(F-Secure uninstall tool for Ver 5.x or earlier)

    This is because the above tools cannot completely remove F-Secure installed from the msi package (example file name: kuic_fsavcs7.1*.msi). In place of them, please use the Add/Remove Programs tool found in the Control Panel.
