When I last booted my computer the windows security alert (red shield with white X) appeared in the bottom right hand corner of my screen. When I checked it said avast might be out of date. I immediately re-registered the product and obtained a new licence key thinking this should solve the problem. It didn't the alert remained visible. I have automatic updates switched on but I still went to the update now links and downloaded everything available this still made no difference to the annoying little red shield. I tried rebooting the computer but nothing rids me of this Windows security alert. I have even tried running a full boot scan but the alert will not go away. Please help ...
