Lenovo One Key Recovery does not work with Avast

My son bought a Lenovo Laptop with Windows 7 (64bit). There is a a pre-installed program on it calles “One Key Recovery” that should serve as a system backup. However, it doesn’t work with Avast: there is an this message " system error… it missing c:\program file (x86)\avast software\avast\snxhk64.dll on your computer." - but the file is definitely not missing.

To disable Avast’s self-protection (temporarily) does also not help.

Any idea?


I am not familiar with Lenovo & it’s included programs but hopefully someone here will be able to help
