Well 2 things:
1. I hopw you are running the Virus Test system in a VM or an Emulator
2. If you find code wich is much faster in C you could provide it to Fred, maybe he can fix some of the speed issues then^^

=> Do you have some collections or some viruses?

I've got 5 packs of viruses downloaded from the web and P2P. It was all I found, but I bet many of them are just duplicates... I am going to use a virus collection tool to sort them out and keep the database clean.
Oh, and I wanted to ask you guys something: What's better to use? Hashes or data from file? Hashes could be faster, but it does not work for infectors which append data.

@Nik:
I don't think I am man enough to test them myself. I think I'll pass them to my friends

. Just joking.
About the speed, I'll make some demos if I can. The difference is that in C I can load a file in a string buffer directly and I use memicmp to search through the buffer.

Are you sure?

Why the fuck doesn't my quote work anymore?

You don't have to use a string buffer if you use memorycompare. And you shouldn't put a file in a string since the file could contain a null character and then everything will be messed up.

ReadData() is also a lot faster.

Thanks Trond. I sorted the database and unfortunately there were many many duplicates inside. The real number of virs is somewhere about 6000

. But that's a start too.

About the statement, the one that c is faster, I totally changed my mind. In a very long loop, I found out that PB is faster

.

Post by **Polo** » Thu Jun 08, 2006 6:46 pm

It's because, I think, that a C compiler, to optimize the speed, will write the code 30 times if you want to do a 30 time loop.
Er, I think

Inf0Byt3 · Post by **Inf0Byt3** » Thu Jun 08, 2006 6:53 pm

Yes, that could be possible. That explains the "Sacrifice size for speed" option in older compilers

.

Nik · Post by **Nik** » Thu Jun 08, 2006 6:53 pm

Well a good c compiler like gcc wil just optimize the code taht means he can inlien if it helps or he doesn't if it wouldn't help, he probably also does alter the code with !NOPs to fite better into the cache, it depends heavily on the compiler gcc 4.1 for example can even vectorize the code automatically

That's cool

. But I prefer PureBasic over C. I guess I am one of those guys with big ideas but bad practice so I need highlevel stuff to accomplish something...

Can't you download a "Virus Generator", "Virus Toolkit", "Virus Creator" or another obscure software? They are all around the net.

Hmmmm... but even if you keep the virus local and destroy it fast - I'll guess it can be a criminal act? or?

Inf0Byt3 · Post by **Inf0Byt3** » Thu Jun 08, 2006 9:41 pm

What about all that software firms that create antiviruses? They should have problems too

... Anyway, I don't keep them. I am generating signatures and then delete them immediately. So what should I do? Should I destroy them all now and forget about this project? I don't want to have problems :roll: .

NO!

Having viruses on your computer is NOT any legal threat!
I think he talked about using virus generators. And i would again say that its not legally wrong as long as you don't spread them.
