Simple question. Developers PCs have to have free access to network, including servers etc., and they have to have administrative access to perform work effectively.
However developers also use a lot of non-Microsoft tools which are available as GPL, LGPL, MIT, free-for-all etc.
Any of them can actually contain harmful code. Even LGPL libraries someone might use for, say, parsing XML.
And we all know that the the very moment someone clicks "yes" on UAC prompt, or does "sudo", the PC/Server can get compromised. And compromised servers can do a lot of bad things, including information leakage, data loss, etc.
How do system administrators battle these problems? Do you trust antivirus software, other tools?
