Both tools report on the same operating system so it should come as no surprise that they report on the same features in much the same way. AFAIK you can’t copyright an idea, only a process or a product.
If my memory serves me correctly, Killswitch was originally created from Process Hacker with the developers permission, so no Comodo did not copy or steal Sysinternals code or anything else, all they simply have done is use Process Hacker as a template and springboard to create there own, and for your information most these system/process tools all seem to be pretty much alike in looks and functionality, do a search for these tools and look at screenshots, better yet install and use them, they all pretty much variation on eachother 88)
Maybe instead of jumping the gun and having a rant here you could have done abit of research into Killswitch and these tools, and then posted a civil question asking Comodo why it looks similar to the Sysinternals one, I appreciate you got a bit hot under the collar, but this was not the right way to approach this 88)
Edit: Took a screenshot of Process Hacker forum as proof
The post by AimeeLW has explained why the similarity in the products very well, thank you. :-TU
I don’t think any more explaining is required and I cannot see this topic positively progressing any further forward, so for this reason I am locking the topic.
