My Nod has found some viruses, first four, then three. Only the viruses it found are System Volume Info for each of the partitions. It mentions that they must be probably modified (probably modified Win32/Agent trojan). First it found all the four SVI for all four partitions, and on the next scan it found only three. Now, I have no problem with my computer, so far, but what about the future? Do I have to worry? Take Nod out or throw my PC away? Thans for help!
