While trying to download a certain program, both limewire and my avg stopped me to say they detected a trojan horse dropper, so i stopped it and its status changed to "file corrupted". Now, there were many others up for download, but with each I tried to download, the same thing happened. So I was wondering, is there really a virus in each of those programs, or does my computer just think there is because the program is attempting to run on my computer? Help would be much appreciated!
