A computer that is equipped with relevant GPU to mine scrypt coins is much harder to find. A virus that utilizes GPU is much harder to write

CPU is too slow to become a problem with scrypt coins. Have you ever mined a scrypt coin using CPU?
I'm referring to mining using GPU; I understand that mining scrypt with CPU would be fruitless, even with 100K+ nodes. A few notes; once a system is infected it's no more difficult to mine with CPU than it is to run a silent CMD with an infection package and mine using GPU (it's the same thing from the virus' perspective). As far as finding suitable GPU zombies; that's not very difficult in today's market of directed infection. Going after architecture firms, marketing companies, and AV outfits is a quick way to guarantee quality GPU's. There is the common flaw of hitting nVidia machines, but with a large infection that wouldn't be a huge concern.
I said that: A computer that is equipped with
relevant GPU to mine scrypt coins is much harder to find. Do you remember that cgminer does not work with on board GPU or every GPU on the market?
If you write such a virus, you may know that the effect will not be high. if you are a virus writer, you may find that it could add some KH/s to your mining rigs. It can not be used as an effective way to perform 51% attack. However, if you want to attack Quark, you will find that it is too easy for you. Every computer can be used to attack Quark. If someone want to control Quark with 51% attack, it is very serious.
Quark is vulnerable actually.
