Reason not joining before. I was sometimes asked at the other forum by some developers to think about features and functions, so all free time was already consumed. With Vista most of the HIPS programs started to decay. So the programs to play with decreased. After Google launched Chrome, I was fascinated how they used existing OS-features (Low IL, job objects, alternate desktop) to build a sandbox in Windows. So my attention shifted from third party security applications to windows build in features.
With the strict rules (not to post video's of user test, no malware) and kicking out members with a strong opinion (I am not agreeing with their opinion, only reading their posts), made me a lurker on Malware tips. When they allowed Cruel sisters video on latest ransomware, I realised that this forum has more interesting reads on malware et cetera, so I decided to join in.
