Greetings. I have been an Avast Free user for yonks but have recently been plagued by a new problem when installing Avast on refurbished (something I do for charity) computers such as the one I am on. After the usual process of installing, rebooting etc. the icon appears in the system tray with a small 'no entry' sign, no providers running and nothing I attempt can get it going except, once or twice, by itself. This PC has Windows ME running. There was a disagreement earlier with Skype but I still have the problem now Skype does not load at boot. I have uninstalled and reinstalled Skype, repaired it, updated it, said nice things to it, all to no avail. What am I doing wrong, please?
