I had a window pop up yesteday from the malware system i use, this is malwarebytes, a free system. It said i had some corrupt files that needed removal. I agreed to the removal and since then i cannot open any applications. I was using firefox as a browser and when i try to open this i just get a window that says choose which file you want to use to open this file, but none of them open it. If i try to download and click run the same thing happens. If i try to open office word, or any windows applications i get a box that says application not found and in the control panel if i try to open anything i get a window that says:C:\WINDOWS\system32\rundll32.exe application not found. I cannot open system restore to try and undo what i did as this opens a window with the same message. I have searched my pc for EXE files and am informed that there are none, presumably this is what i had removed, but if i cannot download anything how can i get them back? Can you help me?
