Kaspersky wont install

I have recently purchased Kaspersky 2009 anti-virus but when i come to install it, it tells me that avg 8.0 is still installed. I have uninstalled avg through control panel and ran the avgremover tool from grisoft but this does not solve the problem. Im running windows vista.

Thanks

 

Have you tried installing Kaspersky in safe mode,

SAFE MODE

Reboot into SAFE MODE

1/Click Start and then click Turn Off Computer.
2/In the Turn Off Windows dialog box, click Restart, and then click OK.
3/As your computer restarts but before Windows launches, press F8 repeatedly.
4/Use the arrow keys to highlight Safe Mode, and then press ENTER.
5/If you have a dual-boot or multiple-boot system, choose the installation that you need to access using the arrow keys, and then press ENTER.
Note: If Windows launches before you can choose a safe mode, restart your computer and try again
PS/ Sometimes it maybe the F5 key
