Every so often I get a red rectangle on the screen telling me that my login & password has changed and there is two spaces to enter these and cancel & Ok buttons. I always cancel or close the box as I assume it is malware but does anyone know what it is? There is no logo in the red box.
I am running Vista on a Toshiba laptop with Avira and Malwarebytes installed both of which I have run and they have not picked this up.
Thanks for that - had a look through the Processes but as I don't know what many of them are it was hard to see if anything was running that shouldn't be. The data drive isn't password protected. I woud have thought if it was a legit operation it would have some recognisable logo on the login splash panel?
