Hi! I too received the same notice, rendering the program useless. I am fairly certain I downloaded a virus or malware. I have tried most of the online virus scan programs without success.
When I attempt to reinstall Avast, the installation is allowed, but as soon as it tries to load, the executable file is deleted.
So far, no malware has been detected by any of the other anti virus programs I have tried, but I still cannot install Avast.
I am running a PC clone with an AMD processor, XP Pro sp2, and have been using Avast Home for at least 5 years without any problem.
Help please!
Thanks.
Roger
