How much security Free version offer

Hi,

I have small home based data entry online business. And I have free version of avast program. Recently I have faced some malware program in my computer and I need to format and re installed all things again. Now I am afraid about my system security. How much and how long it may secure my system?

Thanks

You do know that your not allowed to use the free version in a business environment.

@craigb, That’s why I am buying paid version. Can you please provide me the source to buy? I am talking about valid source.
