I keep getting this big red box popping up on my computer, every 60 seconds or so, or every time I change pages or go to a new website. The voice also screams "Threat Detected". I have just, within the last few days, re-registered for the 2nd year of free Avast. I have run the update. I have run a Quickscan twice, a full scan twice, and also run a quickscan and a full scan of Ad-Aware. All to no avail. When I ran the first full scan of Avast, some objects were found. When I tried to quarantine them, it wasn't clear whether or not anything happened. I wasn't able to do anything further after attempting to choose this option. With Ad-Aware, they found some items, and removed them. The next time I ran both softwares, nothing was found. Still -- I get this message. Total time spent yesterday trying to fix this problem -- 7 hours. Total work done -- none. I own a commercial digital photo lab with a full-time tech. I am not a pro, but he is. I had him spend part of his day yesterday trying to fix this. He can find nothing wrong. Every time this message pops up, I am offered the option of getting further information. When I try to do this I am directed, not to a site where this info is shown, but to a site which pressures me to buy Avast's $29.95 upgrade. I now think that this "threat" is a cynical ploy on the part of Avast to get me to buy their upgrade. If this is true, I will promptly unload this software, and go back to the despised Norton. At least they are upfront with their relentless pressure. WHAT IS GOING ON??
