I had downloaded and used AVAST [anti-virus] for some time now. I have scanned for viruses before with everything turning out to be normal but then out of nowhere I get 8 viruses and 206 warnings today. My mac is a Mac OS X and has no actual symptoms of a virus. It is acting perfectly fine, it's not taking a long time to load nor is it acting any differently since I have received my mac. I simply scanned my mac with AVAST and it tells me i have viruses. I tried to 'delete' these viruses with no such luck. It simply tells me that '1 did not allow the operation' .These viruses come up as ; Tracur [Trj] on my screen. I assume someone in my family must have downloaded these viruses through limewire or frostwire. Other than that I do not know how these viruses made got in my Mac. Obviously I do not want these viruses to stay or corrupt any information on here. So instructions on how to properly deal with this problem is necessary for me. No one in my family has experiences with macs, or any kind of computers to be truthful, so specific [ as in step by step ] instructions on how I should handle this situation would help much more than a simple two word answer.
