after downloading a torrent i attempted to open the file with Winrar to extract, afterwords i find that the aplications .exe and other such files origional shortcut icons were replaced with a miniature picture of the Symbol of the program Winrar on a sheet of (white) paper. and was confronted with an issue as a window poped up stateing that: "C:\bla\bla.exe the archive is either in unknown format or damaged" most of my computers file shortcuts and programs also were oddly converted to this and gave such issues, even when attempting to use my recovery management tools to restore my system to its defaults i found that even this and all of the files that could influence my disk (Cleaner/ Defragmenter ect.) were also effected. What should i do?
