Is formatting the harddisk completely really effective in removing any and all types of viruses on it?

Suppose one day i find out there are 45 viruses in the C: drive of my pc, where the OS lies.and i am formatting the whole harddrive. Do all the viruses get destroyed, or do their remnants still be there in the harddisk?

Is formatting the harddisk completely really effective in removing any and all types of viruses on it?
It depends. There are different types of formatting. Some will completely erase everything on the disk - even the information in the boot sector where some viruses can be found. There are other "short cut" formatting options which may not totally erase everything.





If you indeed want to start from a totally blank disk, then you should delete the main partition which should be an option at the beginning of the reinstall of the operating system. Then tell the system to create a new partition and perform a total format of the partition upon which the operating system will be installed. And make sure you reinstall the operating system from the original CD and not from a backup since a virus might be in the backup copy.
Reply:Yes it will but you will also lose everything on ur hardrive backup ur data and have it scanned at a computer store before you restore it after reformating the hard drive

Reply:try to format all the both C %26amp; D drive which will be good, any one temp folder will also carry virus to next drive, once C drive is formated all the virus in C drive will be deleted
Reply:On the rare occasion that I have gotten a virus, I wiped the hard drive using KillDisk then I reinstalled the OS.
Reply:Yes because it deletes EVERYTHING. If you do not know what your doing, take it to the local computer store oir risk making a doorstop!
Reply:Well, yes in deed, there was a time that we suffer MBR Viruses (Master Boot Record), the virus writes by itself in there, and you have to restore the MBR, your information was clean, but without the MBR you will be not able to boot.


This usually happens 10 or more years ago, we now have Motherboards with MBR Virus Protection, anyway nowadays theese virus doesn't exists...so, this is kind of useless.





So, yes, formatting will erase any virus that you may had.





Thanks, regards.
Reply:Yep. Everything gone. The PC is reborn.
Reply:yes it does. also format you mbr (master boot record) if you really want to. some virii do attack the mbr.
Reply:Formating of drive is not complete soulotion for virus removing.


virus in memory and boot sector is not clean until you clear your boot sector form viruses. with a clean anti virus boot able CD.


ii. Or destroy all partitions on your hard drive and creat new from DOS boot able CD.


you must destroy and create your partition from DOS bootable cd.
