CDROM-Based Virus Scanners?

Posted by Cliff on Thursday September 19, 2002 @01:31PM from the hands-off-bug-hunting dept.

cheros asks: "Pretty much every virus checker I've seen requires installation of a couple of MB worth of data on the HD. However, in a controlled or accredited environment (say, a hospital) installation of external software can invalidate the build, and the checking process can adversely affect timing (in, say, plant control systems), so I'm looking for a virus checker that works from a CD. This obviously means the CD needs updating when new signatures come out, but at least it's a 'hands off' sweep of the system that can be done during maintenance down-time (and assures me that the virus software itself can't compromised). The only workaround I have at the moment is that critical system files can be checksummed to prove integrity (MD5 is your friend ;] ). That's OK for the systems that are fairly static (no, not blue screened, less data changes on the disk =] ), but systems where config data changes (say, a DDNS) are less easy to check. It's mostly a Windows problem (with &^$$& locked files being a pain), but the same situation can arise on any platform. Got any ideas?"
