Actually, you'd be surprised (or I would assume you'd be) at how many of the helpers/experts here at the forum run on free software. A large chunk of the HJT Team, Moderators, and even some Admins here run on free antivirus programs. The two most popular (and powerful in my opinion) are AVG Free (By far the most popular among the HJT Team and such helpers) and Avira's AntiVir (I'm pretty sure I saw an admin who has this program listed as his AV in his profile). It is entirely possible to keep a fully clean machine without paying a cent for security software. Take for example myself. I use the following:
AVG Free Edition
The Multi_AV Tool
Sunbelt Kerio Free Firewall
Ewido Anti-Malware
Spybot S&D
Ad-Aware SE
Windows Defender
A-Squared
Spyware Blaster
Spyware Guard
and the HOSTs blocking software.
Every single program on that list is completely free and in conjunction with each other, keep my computer 100% clean. Now, this depends on your Internet habits. Being the teen that I am, my habits are probably average (if you consider online gaming bad, then my habits are bad), so most people should survive if they utilize the free tools out there and use common sense on the web. In regards to SuperAntiSpyware: I have tried it. Did I like it? No. There are several reasons for this:
1. Its scanner tooks years to scan my relatively small computer size; not to mention all of my other AS programs managed to scan my computer quickly and effectively.
2. Whenever I tried to end SuperAntiSpyware during a scan, my computer would semi-freeze. I'd have to use the taskmanager to end it. After SuperAS was stopped forcefully, my computer would stay in a sluggish, nightmaric state and I'd have to reboot.
3. The monitoring features consumed a lot of my system resources (and I have quite a lot) and slowed my computer to a point where it was more benificial not ot use the program.
All in all, if SuperAS can be made lighter and faster, it would gain potential to compete against Ewido, Ad-Aware SE, and such programs.
