Facebook has virus detection and it will scan your uploads and if they find out that the file you're trying to upload has a virus, they will stop you from uploading and ask you to scan your computer for virus and then re-upload.

Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

computer A has many viruses with photos

i will upload to facebook hosting from computer A

view or download photos on computer B, can computer B get any virus from computer A ?



Computer A will be burnt with fire after using. Smiley


WTF ? Is it infected by AIDS or EBOLA that U'll burn it with fire ? Just format it, connect it to internet and run a full node on it.

Photos can never infect you because they cannot contain code.

How in hell can a picture have code  Roll Eyes

Effectively you could embed anything you like in a picture. For example in the EXIF data. If a photo viewer in fact has a vulnerability you could (under certain circumstances) cause a buffer overflow and execute arbitrary code on the targeted machine. It wouldn't be the first time that something like that is being used to take over a machine.
That has happened a few times through the history of computers!

As malware reverse engineer then i can say that malware almost never copies itself to image formats, only exe files and rar
sometimes it automaticly seeds a torrent file also
