Well, it looks like I spoke too soon.
I have just switched on today and once again the top of the user interface screen is Green and states ..."SECURED - your system is fully protected". And the Ball icon at the bottom of the screen is Orange and not Red. BUT when I hover the mouse over it, a message appears saying ..."Avast! Antivirus: WARNING, your system is unsecured".
There is never any FIX NOW option on the interface. I have run a full scan - and nothing is found. I don't believe that the system is unsecure - I just think the message by the ball icon is inconsistent and WRONG !
Tarq57, in answer to your question - I was previously using Norton Antivirus. Before installing Avast, I used the latest Norton Removal Tool . . . TWICE (as recommended by Norton themselves).
I really thought that Avast would just provide a solid, easy, fault-free AV solution, but now I am left wondering whether to return to the awful Norton . . . at least it didn't keep telling me my system was UNSECURE when it isn't !!!
Any further help would be appreciated.
