The opening poster asked:
Has anyone had an infected Mac? (+just curious+)
I replied:
Yes, my Mac and others nearby were infected.

You were not infected by a virus.
On 2000-03-28 some Macs in my area were infected by a
macro virus then identified by an antivirus software vendor as W97M/Proverb. According to notes from the time, protection that was both limited and not through the usual channels became available on 2000-04-07. Some technical knowledge was required to install that limited protection; the workaround was not scripted.
Protection that was greater, and through the usual channels, came at a later date.
In my experience there's some peace of mind in adding third party protection against malware.
An alternative for the present is to rely on the very basic protection that Apple integrate in the OS, then follow the debates re: whether threats exist.
Beyond the present: if/when a threat exists you're unlucky enough to suffer from malware — and if you opted to be without additional protection — then you should be prepared for the possibility of your situation being less happy than those who opted for the additional protection.
Hope that helps,
Graham
