Hi to you jennyjoan.....It may sound ridiculous, but I am pleased that you have found malware; it means I am on the right track.:-)
I would suggest that you do further scans. It's a bit like vacuuming a room; because the second time, a few hrs later, you will still find dirt and dust which wasn't picked-up on the first going over.
Incidentally, I have noted that you are operating with XP. Consequently I say, "Keep it going as long as you can. XP was possible the best that came from Microsoft and providing you have Anti Virus and Malware protection, the operating system could outlast your computer, which possibly has a few years to go before it packs in completely. 30% of Computers throughout the world are still operating on XP....a lot of Businesses are dependent upon the system; hence the reason for MSE support having been extended to July 2015.
Keep posting.
Hans.
