@K to the z, I understand that but very rare happen with me alot, more than once i look for zip file hash on virus total and it give me some file different in name,type and size. wired they can do what they can will never come close to finger-print creation of Allah.

you are right 'downloading (multiple) encryption tools might put you on the list of suspicious citizens' how I never thought of that I'll keep that in my mind from now, thanks

I mean if file hash is (J3JRMND) for example and the file infected with w32 virus when I check the hash again will it be the same or not. AND is there any virus can infect the file and the file keep the original hash.

But the hash will change if the file get infected or it can keep his original hash after infected?

@AndySmith, thats a great article thanks. 'this is because many new heuristic techniques that we use can't be included inside the on-demand scanner' I think i'll rethink about my AV.

understand, but let me ask u one last thing IF I used like three programs to encrypt a file for example zip then 7z then rar with three complex random different password will that increase security or not?

IYO what you think is better truecrypt or freeotfe because freeotfe had more ciphers and i can change the salt and add some bits the end of the container, what u prefer?

'The two systems are not designed to work in unison, which might lead to interesting specially-tailored attacks. For example, having a block encrypted by one piece of software and then another might result in a timing attack, or other side-channel attacks.' can u simply explain what that mean?

'If a flaw is found in the cryptographic mechanisms in either piece of software, but not both, you still retain a reasonable expectation of security.' thats what I make it for i truecrypt cracked or if it had aback door or something the attacker still had to pass freeotfe witch he dont know that I use it he might think it just another truecrypt container. right

@Cristian Dobre, can you explain why it adds very little security?

that's tue from now on I'll scan my files hash on line with virustotal and toss my antivirus. and if u had some sites work like virustotal it would be great to share them with us. thanks

that mean I can just check any program I get from a friend online by hash in virustotal, But are u sure that when any file infected with a virus the hash will change or the file could get infected and keep his hash ?
