How would I know if my Mac had malware on it? What sort of problems will occur?
My system is running slow. When opening a new web page takes literally several minutes to load. Can speed it up a little bit by selecting a new wifi connection. Also having random ad click downloads when on yahoo. I heard ere is malware infecting 1:5 macs now. Just read the article about flashback and disabled java. Anything else I should consider?
MacBook, Mac OS X (10.5.8)
