I've managed to get my hands on a really old mac computer that was probably built in the late 90's. The operating system was last updated in 2001 to 10.1.4. The problem is that I'm not sure if it's okay to surf the Internet on this machine. There is no anti-virus security for it; and it's not like I can install Norton on it because the computer would be unable to run it since it only has half a gigabyte of RAM. I would think it would at least okay to browse on Google and access most of the pages that Google presents.
Would it be relatively safe for me as long as I use common sense or is it unsafe. If not, is there an anti-virus software that is made for computers like this?
