How can I tell if my Mac has a virus
I recently opened an attachment to an e-mail that looked like it was from the IRS. Now I am concerned about it. It was a 30.4 KB attachement. I printed it out and it was about 10 pages of gibberish. Top of first page reads: This program cannot be run in DOS mode. How do I know if I have done something bad. My Mac seems to be running just perfect. Thank you
iMac, Mac OS X (10.6.8)
