Hi, my problem is that I can't manually start a scan, because every time I click on Antivirus Free to open up the window that should allow me to "Scan Now", the new window is immediately transformed into an advert for Antivirus Pro which cannot be got rid of - I can only close the window, not just the advert. I don't mind the adverts generally, but this is seriously annoying. Can anyone help me with this? Thanks.

I'm having the same issue.  Keen to know the solution!

Thank you! I will do that, and get back to you if there is still an issue.
