Every once in a while I get someone bringing in their Mac saying they want it checked for viruses because they think they have one. Currently, I just check activity monitor, do software updates, and tell them what is actually causing their problem. Do you think I should start doing a full virus scan if the customer really wants it? The way I understand it, apple blocks certain known malware, but if someone is one of the first to get something, then they have no protection. If you think I should start doing a scan, what tool would you recommend? We get people bringing in their computers with anti-virus programs on them, but a lot of them tend to cause problems.
