Do you get any menu if you right click on the "lock". Try dbl left clicking on the "lock". What happens ??
I had tried that.Weird thing is when I passed mouse over it arrow disappears underneath.
Click Start->Run-> Type "msconfig" minus quotes and click the last tab "Startup". Click "Disable all" and restart PC. Is the lock icon still there ?
***If you have a hi speed connection, turn off the external modem or put the modem on standby since this will disable your antivirus***
Everything seems ok!I really appreciate your help.
