I bought this mac pro about a month ago, maybe less. I bought an antivirus software system even though everyone told me I wouldn't need one (Kaspersky, I dunno why I chose it) Anyway, Today it says it picked up a trojan somewhere (Im thinking it may have originated from my email account because it had the word yahoo on the long file name (uber long file name). It said that it eliminated the problem, but now I'm scared to death. What can I do to know that my commuter is still running top notch and won't now be prone to these invasions. Is there anything I can do to make sure the performance stays excellent. Any suggestions at all would be so great, I don't know a whole lot regarding these matters... What should I avoid? besides file download (I'm not totally hopeless). And how do I check that the comp is still factory fresh and uncompromised? I know my cry for help may seem a little vague, I'm just freaked and I want to make sure this 2000 dollar piece of machinery is as strong as ever. If anyone can take the time to make a few bullet points I would be eternally grateful. Thanks guys and girls.
