Sometimes I repair my friends PC's. It leads me to the question. Let's say I take their Windows boot drive from thier PC, and add it to my PC as a NON-booting drive. I scan it with ESET, will it repair that added drive PROPERLY? (even tho it's a BOOT drive for another PC) I need an answer at this point, before you read further please. Typically I use a free AV on such machines, such as AVAST or AVG. But I have ran into a rare case, the PC can get no further than the LOGON screen. The mouse and keyboard are then non-funtioning, but the PC is NOT locked up. The mouse and keyboard are good, as they work in the BIOS and Dell internal hardware diags. The units also work on other PC's, as I tested just to be sure. I know the machine is NOT locked up because when I press the power button, Windows states it is shutting down. It must be a unique virus. For now I just backedup their data on my own machine, and about to reinstall the OS once thier Windows BOOT cd comes in the mail. ANother question: Can ESET scan network drives on another PC and repair them properly? Assuming the permission rights are given to change data on such drives.
