Problem with AVAST installation

Hello!
My operational system - Windows XP Pro SP2.
I had problems with installation of antivirus AVAST Home 4.7.1098.
Before I had an antivirus Kaspersky 5.
Before installation AVAST Kaspersky has been uninstalled and now in folder Program files Kaspersky’s folders are not present.
Then has been installed AVAST. Installation has passed normally, but at start of system and AVAST there is a message that Kaspersky’s any drivers work and consequently some services AVAST will not be started.
Prompt, please, how to find and remove Kaspersky’s these drivers that AVAST has worked normally.
Thankful in advance!

  1. Use this util
    http://www.ice-kav.com/downloads/util/KAV_Registry_Clean.zip
  2. delete files
    Kl1.sys, klick.sys, klin.sys, klmc.sys in folder …windows\system32\drivers
  3. delete registry keys
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Kl1
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Klif
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Klmc

and

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet…\Services\Kl1
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet…\Services\Klif
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet…\Services\Klmc

Please do NOT use Kaspersky anti-hacker together with Avast!
It seems that Kaspersky writes something in the registry that is picked up by Avast! that makes Avast! think there’s another AV program installed.
Allthough this is not the case (KAH is a firewall, not an anti-virus prog) Avast! will nag you about this. Read here : http://forum.avast.com/index.php?topic=13835.0

I think it’s all.

Hello!
Many thanks for the help!
The rests of an Kaspersky antivirus managed to be removed by means of program KAV RegistryClean and manual cleaning of the register.
Now AVAST works normally.

Glad you finally win! Welcome to avast world! 8)
