I recently uninstalled bitdefender antivirus v10(worked great), and installed antivirus 2009(using windows xp). It seems to run fine until I use programs such as windows media player or roxio creator or put a disc into the dvd drive. Everything freezes up. My dvd drive will also not recognize any disc put in it. I have to cut the power to restart. After restart everything is fine until I use programs again. I can surf the web ok, but seems to be issues with these programs running or using the dvd drive. I have not tried other programs yet to see if it happens to them. I tried uninstalling antivirus 2009 and reinstalling v10, but no icon appears in the system tray, and when I double click on the shortcut icon, nothing happens. I would like to stay with antivirus 2009, but seems to be some issues going on. Any ideas?
