Thread: How to erase entire the files from system earlier return set up of Windows 7?

There is few trouble with my system really my antivirus have caught few Trojan and viruses on my system but the antivirus is ineffective to erase entire viruses so i decided to reinstall the Windows 7 Pro 64 bit. But thing is i require to withdraw entire the documents so that the virus should be withdraw totally from my system. So, is there any way by which i can totally kill entire the files on my system and then start the re-installation o windows 7?

It took around 2 hours on my system to altogether blank the disk, but it also reckons on the settings yoh have select on your system and few other elements like your machine kind and the speed of the system. I think you have high speed processor that’s why it took only some seconds to erase entire the documents from the disk.And other matter which can involve it is the kind of HDD and the program settings etc.
