I found a great site that checks files for viruses. If you have a file on your computer that you worry might be a virus. You can upload it here to be scanned by several (32, I think) different virus scanners. I checked out a file called “Good Karma” a friend, Joyce, received as an attachment. It was NOT a virus.
