I have a MacBook Pro, which I purchased in July. I haven't had any problems with it until recently, and I'm thinking it might be a virus. The MacBook: -goes much more slowly when using the internet than it used to -will only allow me to use one application at a time -will not print anything -all of the icons on my desktop disappeared after I did the Quicktime Update last night I still have all of my files as far as I know, but why would they just randomly disappear from the desktop? I don't have any virus software, but I have never downloaded anything from the internet other than Microsoft Office Software from my University and files that were e-mailed to me from trusted sources (i.e. test reviews, syllabi, etc). I was told that Macs rarely get viruses, but I have also heard that college campuses are targeted with Mac viruses more than any other place. Does any of this sound like a virus? And if so, is there anything I can do to fix it other than calling Apple Tech Support and having them erase my hard drive? Any help will be appreciated!!!
