Which is a good antivirus software?spyware removal

I have a legal and moral obligation to keep my pc 100% clean. And I use an antivirus/spyware program out of Beijing, China.

http://www.filseclab.com -- This program has kept me 100% clean for the past nine years.

Twister Anti-Trojan Virus is absolute state of the art technology that has a real time scanner

that really works. Will scan your memory on start up and continues to run in the background

while you use your pc. Plus this software uses very little CPU resources.

Some examples of how great this program is. If you open a webpage and there is a virus or

spyware embedded in the webpage the scanner will catch the virus in a second and clean.

If you download any type of file including music or a zip file and there is hidden embedded

virus in the file the download will stop and the Twister will clean and stop the download.

I had an experience where the software I download the company used another installer other

then their own. The installer had hidden embedded virus in the installer program.Twister found it and cleaned, plus ended the installation and traced it back to the installer software.

(I wrote the original software company and they now use their own installer).
