I have tried to reformat my harddrive using the DOS prompt format c:, but when asked if I want to proceed, and having typed yes, I get the following: "Format cannot run because the volume is in use by another process. Format may run if this volume is dismounted first. ALL OPEN HANDLES TO THIS VOLUME WOULD THEN BE INVALID. Would you like to force a dismount on this volume? (Y/N)" At which point, I type "Y". I then get: "Cannot lock the drive. The volume is still in use." PS. Need to reformat as my laptop is full of spyware cr*p! PPS. If I can get my reformat done, can anyone recommend a cheap and effective protection against spyware on-line? Thanks!!
