DOS virus scan software
I'm running a 386/25 with Dos 6.2 for billing. Recently it has been
having problems with bad sectors on the drive showing, and refusing to boot unless you boot off a floppy and do a sys c: from the A drive. Now it will not boot from the hard drive at all. Luckily I copied my customer files before this happened. But there is alot of other stuff I would like to get off it. To rule out a virus problem is there an up to date scan program I can get that will run from a floppy on a Dos machine? Thanks, Lenny Stein, Barlen Electronics. |

AVG will create a boot floppy with a virus test and it's free. http://www.grisoft.com/us/us_index.php N |

How would a virus get on the machine in the first place? Obviously it's not on the internet, and if it's just for billing it seems unlikely contaminated disks would get in there. |

I tend to agree with James, but since any anti virus program that could be contained on one floppy would necessarily be very limited, I would remove the HD and attach it to a system as a slave drive. After having done so, I would run the A/V program on this system and direct it to scan the slave drive. The new system would undoubtedly have more complete virus definitions and if there was a virus is more likely to detect and remove it. That being said, your symptoms sound an awful lot like a HD about to fail. |

If this machine is not on the net, or used for running any external
softwares, I would be inclined to believe that the hard drive is failing from age and use... -- Jerry G. ========================== "Lenny" wrote in message m...

Boot the hard drive up on a HD diagnostics disk, such as
SpinRite by Gibson Research Corporation (www.grc.com) and test the drive for physical integrity. This is probably a very old drive, on a definitely very old machine. Your drive had a MTBF (Mean Time Between Failures) of less than 5 years of continuous operation, and you have likely tripled that time. -Chuck Harris Lenny wrote: I'm running a 386/25 with Dos 6.2 for billing.

Well we have alot of old floppies floating around here that have
questionable data on them. They get plugged into machines sometimes and its entirely conceivable that some unknown stuff could be spread around this way. Whether a Windows based virus would affect a Dos machine, I don't know but I suppose anything is possible. I don't want to take the magnetron magnet to them until I know whats on them. And if I could scan them first that would be great. Lenny. "James Sweet" wrote in message news:RYncd.5464$232.2958@trnddc09... "Lenny" wrote in message m...

The new system would undoubtedly have more complete virus definitions and if there was a virus is more likely to detect and remove it. That being said, your symptoms sound an awful lot like a HD about to fail. I agree with this suggestion, and you could actually do it on your current system. Just pick up a cheap hard drive somewhere (I have a 525 MB you can HAVE) and reinstall DOS on it. Boot to that drive, with your old drive mounted as the secondary drive. This way your old drive will be recognized as the D: drive. Once you're booted up to the new C: drive, you can examine the old drive and see if you can read it. If you can, you'd better copy everything to the C: drive right away. If you have a newer computer you could certainly install this disk in it, as a secondary drive and use any more modern OS to try to read and copy the old drive contents. You can certainly check for viruses this way, but it sounds like this is a much less likely senario than just a failing hard drive. - ----------------------------------------------- Jim Adney Madison, WI 53711 USA ----------------------------------------------- |
