There is a virus in the computer hard disk, and the method of removing the virus with floppy disk.

Who uses floppy disks to kill viruses now? This is an old story. Many motherboards have no floppy drive interface at all. Few antivirus software vendors use floppy disks now. There are three disadvantages in using floppy disk to kill virus:

First, the quality of floppy disk is unstable, so it may be unreadable after reading and writing several times.

Second, the floppy disk capacity is limited. At present, a virus database has at least 7 or 8MB. If you want to use floppy disks, you must have at least 10 floppy disks.

Thirdly, antivirus under DOS is very limited in identifying and killing some new WINDOWS viruses and Trojans. Floppy disks can only kill viruses in the boot area.

At present, anti-virus software is generally installed directly in the system, which can directly kill viruses, and cannot be cleaned at one time, and then automatically killed after restarting. If it still can't be cleaned, you have to reinstall the system, then install anti-virus software to update the virus database, turn on instant protection, and then update the operating system patch. There is usually no problem. The key is that anti-virus software should be stationed in the system before the virus.

If you must kill virus under DOS, many anti-virus software provide a U disk version, which is much more reliable than floppy disk.
