I’ve been around long enough to recognize software that will be efficient and software that will cause problems … GrimeFighter falls into the second category… it is a risky download. As to your suggestion to go back and run the program again that caused the problem in the first place is not a prudent path … running the offending program again that caused the problem … now that just does not make sense and one would immediately discount your input. From a practical standpoint, backing up is usually done on a schedule … not every day. As for houses burning down … let me say with all confidence that the odds that GrimeFighter will turn your computer into a boat anchor are 70 out of 100 and the odds your house catches fire in the USA are magnitudes lower … on the level of 3/10ths of 1%. Furthermore … I did not ask for assistance … I posted my opinion as someone who is computer literate for over 20 years and wanted to save other people from suffering the damage GrimeFighter can bring to a personal computer. I say again … I strongly suggest folks avoid downloading GrimeFighter … you are risking a problem with your system.
