It might be part of his role but it sounds like he is expected to do much more than handle broken computers and such. Perhaps he is partly at fault for not raising this with his manager but it is also his managers responsibility to be aware of how much work he is doing in all areas of his positions responsibilities. Given the limited (and one sided) information we have and going by my personal experiences of small companies I would put my money on him being overworked and expected to "do it all" because "how hard is running antivirus to fix a problem".
