Trojan horse Generic YZT

AVG alerted me to the presence of this trojan yesterday. I got AVG to delete it, but it just keeps on ticking. Today I turned off system restore and got AVG to rescan my pc in safe mode. Still no good. According to AVG, the little nuisance has lodged itself in a zipped program file and a couple of restore points of system restore.

I got Zapersky to do an online scan of my pc, and it came up with the following [note: some of the last one or two letters of the trojans' file names may have been inadvertently cropped when I saved the log file to disc]:

Not deliberately bumping this, but I had to let all concerned know that I got rid of the 1st bar trojan. So at least that's no longer an issue on my pc.
