On the main page link that you post, there is not actual contact option.
Yes you can look in forum, yes you can submit a ticket for alert or viruses, but a simple contact for complains?? or suggestions?? there is not actual direct contact the company.

Why I have to manually disable pop up of a software I buy?? I never have to do that with any other software I own.
I don’t think is the correct way to do business. or promote your software.

I just got the antivirus, I didn’t purchase clean up or anything else, why I receive pop up of things I didn’t purchase nor care to do it.

The pop up is very clear and it work just like any other spam ware.
‘We checked your system and found XXX error, please upgrade to this or purchase that to fix it’

That’s not cool IMHO.
