I need some info about viruses designed for mac. I just switched to mac about 4 days ago from being a pc user and have been reading about viruses on this site for hours, and how I can protect my computer. Quite frankly I’m a little freaked out. I downloaded ClamXav and it works great at scanning my mac for viruses. However I felt I needed something more. Something that would detect viruses, trogans, spyware, and alert me immediately. So I downloaded an application recommended on this site. I don’t remember the name of it but it was like ClamAV or something like that. I downloaded it and it was sent to my desktop as a .zip file. Right away without opening it I scanned it with ClamXav and it found one infected file. It didn’t say what it was, just that there was one infected file. So immediately, I moved it to the trash and emptied the trash can. Then RESET my mac to delete it from memory. Should I be worried that my computer could be infected with something even though I did not open the .zip file? I have done extensive scanning with ClamXav to make sure there is no virus on my computer. Also my mac hasn’t been acting differently that I have noticed. Is there something in particular that I should look for? Can you catch a virus just from surfing the web? (Ex. merely opening a webpage from google) Or do you have to actually download something? Any input will be greatly appreciated!
