Mobile Antivirus J2ME

if there was a virus, there are now anti-virus J2ME CommWarriorAntiVirus, Although still simple shapes up, but the source code can be viewed and developed their own lho.So allows itself to be learned, even develop.
However, anti-virus page can only detect a virus, CommWarrior only.
To get the source code just looking at http://www.Planet-Source-Code.com.
