There is a free software called Repetier-Host - its relalted to 3D printers and connects by USB to the motherboard of the print. I mentioned on a Faceboob page that I was having a problem getting this programme to work. A few wminutes later I had a Private Message with a download link and a message to say it was the latest upgrade - as its a free programme I saw no harm in this and downloaded the file. Despite the files title it was not Repetier and has it was being installed a Norton pop up advised a file was not safe and had been removed. I have uploaded teh file named by Norton - to Norton to check it and deleted the application which seems to be a scam. However, about 3 days later I rebooted the Windows 7 PC and found no internet connection... no light on the USB dongle then trid the mouse to click the wifi icon to troubleshgoot... no mouse - no keyboard no USB ports working. I am not bright on computers but a friend pointed me to a guy in a local store and after 3.5 hours, he gave up and could find nothing to re-enable the USB ports.Forgot to mention he got into the computer by using the old mouse and KB which did not use USB and those round purple and green plastic covers. Without a wifi connection - its virtually impossible ( for me) to get anything from Microsoft to deal with USB drivers... and Heur.AdvML.B seems to responsible.
Thats the background.... question is what can I do to get the damaged USB drivers replaced by good ones - and how do I get around no USB access?
