Well I managed to nail at least most of the trojans through DOS... and in actuality it was a different trojan.. a trojan.proxy.bcd or some such. attached with ADS to a system restore folder. Within the past couple weeks.. meaning they got nailed with it after I returned it to them last time.

However, the Limited user still won't work. And I am at a loss. Not that it matters much, I was going to format and put on FAT32 anyways. It appears the only infections that are giving them trouble are the ADS ones... and you can't infect FAT32 through ADS.
