I'm looking for a corporate anti-virus product that has proactive detection of USB viruses--without having to enable autorun on computers. Does anyone know if ESET can do this, or will it only detect viruses if you have autorun enabled, browse the folder with the virus or try to run the virus? I can understand why some vendors wouldn't want to force a full scan of any USB storage that gets inserted (especially if it turns out to be a TB drive full of small files), but it seems like with the massive increase in malware spread via USB, it wouldn't be unreasonable to expect (at a minimum) anti-virus to detect the USB Storage service starting up, check to see what drives it mounts, scan those drives to see if they have autorun files, and then scan any files that are referenced by the autorun. It would have minimal impact on performance. I think users expect that if they plug in a storage device into a computer with updated anti-virus, it will tell them if it is infected--unfortunately, the software I've tested so far all seem to not meet that expectation. Any idea if ESET will pick those up?
