I have two hard drives on my PC and both (a) are partitioned (b) have windows installed on them (c) have partitions having data. 2. My query is Whether a virus on ONE hard drive can corrupt windows/data on the OTHER drive?? 3. If yes, what is probability?? (a) high (b) medium (c) negligible

Not knowing your exact setup, I'll venture a scenario. Drive 1: Partition 1: (C)2kPro Drice 1: Partition 2: (D)Data Drive 2: Partition 1: (E)Win98 Drive 2: Partition 2: (F)Data Whichever OS was running (C or E) will have a high risk of being infected. The partition with the dormant OS will have a medium risk (I would treat it as a high risk factor until the exact virus were identified). The data partitions are at low risk if you are ONLY using them for storage. Proper procedure would be to open the case and unplug power and eide cables to 1 HD. Boot and scan with a reputable AV package. Open the case again reconnect the HD and disconnect the previous one. Boot and scan again. This will require the AV software being installed in both OS's. The AV software will identify the exact virus by name. Go to Norton's website and look it up, they have removal tools for just about everything, that you can DL to floppy. http://securityresponse.symantec.com/avcenter/tools.list.html Boot with A: as first boot device and the DL'd Norton file on a disk. The disk is bootable and will remove the little nasty for you. Disconnecting the HDs is not a necessity, I do it simply to isolate them and prevent the virus from jumping. Some viruses can jump, some can't. I'd isolate them until you find out what you are dealing with. _________________________ The internet is no longer a toy, it's a COMBAT ZONE!

Drive labeled C is default and therefore can be attacked more easily.Although they can scan your system for all HDD which you have and go from there. 31337
