Avast is supposed to work with Windows 7 and 7PRO, which is why I subscribed. HOWEVER, we have had two disasters:
- Avast suggested updates, dated prior to 2020. These damaged one 7Pro system resulting in touchpad/mouse issues and blue screen if you try to shut it down or close the laptop. These were unrepairable.
- Avast suggested a system cleanup to speed up the system. When run to killed one laptop.
Both laptops were high end Lenovo Thinkpads with Windows 7 Professional.
Therefore if you bought Avast for your Windows 7 systems, DO NOT DO AVAST UPDATES OR SYSTEM CLEANUP TOOLS>
