I just downloaded this software for trial and it starts, but I let it run overnight and in the morning it was still at same spot and when I did a control Alt Delete, it said TDS (not responding). I'm trying it out because I'm sure I don't have a virus, but my computer has something gone wrong and I was told it was possibly a Trojan. It's exceedingly slow all of a sudden and I've done all the usual maintenance (delete temp files, scan disk, defrag). The hard disk seems to be working when it shouldn't and I was hoping maybe this was the answer. Any thoughts or ideas about what I can do?
