(PC) Message-ID: <0002.8907211953.AA01786@ge.sei.cmu.edu> Date: 21 Jul 89 07:41:20 GMT Sender: Virus Discussion List Lines: 28 Approved: krvw@sei.cmu.edu We have a virus on our PC, it is not a new one I think, but what to do? The virus infects all disks,5 1/4 and 3 1/2 and the harddisk. We can find the infected disks by using chkdsk. chkdsk gives 1024 bytes bad sectors on a infected disk. When we use that disk in another computer then we also have 1024 bytes badsectors on that harddisk. When we use format on an infected computer, there seems to be nothing wrong, formatting goes well, but when we use chkdsk it gives 1024 bytes bad sectors. So far I know that format, copy, diskcopy can't be used anymore and xcopy doesn't work anymore. I now low level format the harddisk and put the original files on it and we format all the floppydisks with badsectors. But when someone uses a disk with bad-sectors we have the virus back again. We also can see the virus when we using backup or pcbackup etc. then there is a little ball bounching over the screen. I also happens sometimes ! when we using copy, diskcopy or an other copy command. I don't know the program that infected our system, but we have a lot of work to deal with it. Is there a easier way to deal with the virus, except low-level format.
