Hi Ed - Thanks for your input. However, I am not that much of a greenhorn to do what you suggested. And I do have rkill. But I shall have to wait for the next time the thing pops up; it has not appeared in the last day or two. By the way, the program looks more genuine than any of the other malware items that I have come across in the past. It styles itself "Microsoft Partner", carries the BBB seal of approval, has the Microsoft emblem in the exact italics slant, etc. Since I have not clicked on it I could wait for it to reappear. But I would suggest that you have a look at it before you class it with all the other scams whose only interest is cashing in on the fears of the newbies. I tended to automatically erase it (with Your Uninstaller) but waited for someone to actually analyze it. Tried Revo before your reply was posted but they did not find it. To recap: it is called RegCurePro, and I am still wondering if anyone else has encountered it. And to clear things up: one of my computers really has an awful lot of junk which I am not really able to distinguish from the necessary items - so much so that it refused to connect to WiFi in various locations (such as a Starbucks on the Upper West Side in New York). I have run CCleaner but it did not help much. So if you have a suggestion for a real cleanup -for free if possibIe - I shall be very grateful. - Amos
