So I think my home machine has a virus. A box/window has appeared on my desktop in the upper left corner. I am running Vista. It covers the icons my desk top. It is about 3x3 inches and it is tan color with no borders. It looks like a locked window for an application running in the background. If I click my desktop shortcut all windows are minimized including this box, but when I open any other window the box appears again. I am new to vista, so I am not that familiar with the services. I have my machine disconnected from the net and it is being fully scanned by Norton and also SpyWare Doctor 6. I am away from my machine, so hopefully one of these scanners picks it up. Anyone encountered this sympton before? I haven’t noticed anything else yet.
