Defiant, as far as Sophos is concerned, the answer is a BIG no. I work in a mac environment, in a school district. We’re in the process of moving from Sophos to another solution, largely due to anomalous issues we tied back to Sophos. Their products are okay on PCs. It was just on the macs, and the xServes, that we had problems. Our mac server guy uses their name like a swear word, if that tells you anything. It’s not that they’re completely awful, either. But, when you combine the sort of performance we had with their product, and the FUD, a sample of which is in the article, I’d just say no. To be fair, we don’t have torrent-related issues in the district, or much like that. Our primary reason for antivirus on the macs is to protect the few PCs we have. But I wouldn’t worry so much about it at this time. I hope that helps.
Thanks guys for the answers. I appreciate the information. I think I probably don’t need antivirus right now, but I understand that some people use it out of an abundance of caution. I’m glad I don’t absolutely have to use it yet, one less thing to worry about on my Macs. On PCs, the antivirus issue has become less of a problem, with stronger CPUs and free programs like Microsoft Security Essentials. The slowdowns and expense of antivirus protection are far less than they were. But it is still more of a pain than on Macs.
