Hello to you all, new user here. simple question to start with. On start up i have a message from "Avast telling me "i have upgraded my system and this version cannot run. please uninstall and download a new one" Even though i have never run avast before yesterday. The desktop icon is here, i've clicked on it and it seems to have succesfully scanned. Should i therefore ignore the pop up message ? or uninstall and download a new one.
Thank you.
