Avast and a blacklisted program I don't know about
I keep getting messages from Avast to say that they have managed to stop a potential virus-carrying link or program ... sunshinegame which has been blacklisted .... and this happens about every few minutes with a noisy bong bong noise, stopping me from working and stopping my computer temporarily until I get rid of this. I have never even looked up the website/programme they refer to. Apparently the solution is to replace their free version by a paid-for programme.
Is this a real threat or is this simply forceful advertising by Avast?
If I disinstall Avast free and then reinstall it will this annoyance go away?
If I should replace Avast free by some other free antivirus program, what can you suggest .... note I don't need to be castigated for my frugality!!! I'm just becoming a more obvious IT dinosaur who needs advise in simple to understand terms! Many thanks in advance.
