its only helping people, and its not `violating security and privacy` because it wont be recording or reporting anything.
Actually thats not true... even if it did do alot of good, its still useing processing and/or network connections and not to mention it still propogates otherwise it wouldn't even be considered a virus or worm.

Welchia was not helpfull to anyone at all. I've removed this from several people's computers and this worm does not get rid of the backdoors that MSblaster left behind and its method of scanning caused internet connections to crawl on its knees. Also if you look at yahasux... gigabyte says it all, you have a worm which is then replaced with yahasux. I also beleave there was some *cough *cough "accidental flaws" with yahasux which caused some problems. It still spread itself to other users. That ain't removal. This is niether good or really that bad... just something else for the mindless masses out there.

Malware effecting other malware is nothing new either... there have been many occasions of *exe and *com appending virii which had the ability to remove another virus to further place itself on the thrown or show another Author who's boss sort of speak. Another thing is there is always the possability that they could attach themselves to each other without the author or user's initial intent of this happening. And the thing about over-writers is it doesn't really leave much behind, it just replicates. If another piece of malware is in its wake then it'll just get overwritten like everything else.
