Hhmm, I have been dealing with virus issues a lot this year, and I have tried several programs. I read some positive reviews in some of the forums and got the CyberdefenderFree. Yes, it is a little confusing about what is free or not, but the fact is companies need to make money else they can't support the software - and they use all kinds of ways do to that. You just got to know that when you install. I have removed Cyberdefender from my computer (WinXP SP3) twice - both with out problems. So, I really like the Cyberdefender interface, scan times and that it found what I knoew was on the system, including several programs/viruses/trojans that some of the others (PC Tools, SuperAntiVirus and Norton) missed. I used it as a free scanner, but the free version does remove spyware and trojan, but you got to upgrade for virus. Evenually one came along, it caught it, and I bought the upgrade. Ran Cyberdefender after the upgrade, and virus was gone (it got into my rootkit and also got the vundo virus which it took care of. I also like that the upgrade I got came with 24/7 computer help, which was very helpful when I went on a trip, and my wife had a printer problem and called them. They helped her out and had a positive experience with the Cyberdefender help line. So, this is my experience with Cybderdefender - really good software. Granted, different people have different experiences, but this seems to be a good company (website says they are a NASDAQ company) with a valid product. JMHO.
