I am aware of the other thread with this problem however i have tried them steps and it didnt work also im using 2009 not 2008... anyway my bitdefender has been working fine until today where bitdefender stopped appearing in my system tray. Everything is on as its in the task manager and also if i open it, it says its running fine. Also windows secuirty center says im running bitdefender firewall and anti virus...... can anyone help me as to why it is not appearing in the system tray?
