virus protection for Tiger OSX 10.4.11
I recently received an email with a virus from a pc user. Emails were sent to everyone in her address book. I didnt open the file but did preview it. How can I find out if the (or any) virus is sitting on my computer, ready to infect my pc user friends (trojan horse?) I tried downloading Avast, Clam etc. but none of them work on older OSX versions 10.4.11. I am also using Entourage and Safari browser. I cant upgrade to later os as my software wont work with them. So what im looking for is something to check whether I have the virus and then a protection to keep me from getting others (mostly pc, of course). Any help for us dinosaurs will be gratefully accepted,.I inherited this computer so dont know if it has virus protection software already.
