The file is a text file of between 68 and 128 bytes [6] that is a legitimate .com executable file (plain x86 machine code) that can be run by MS-DOS, some work-alikes, and its successors OS/2 and Windows (except for 64-bit due to 16-bit limitations). The EICAR test file will print "EICAR-STANDARD-ANTIVIRUS-TEST-FILE!" when executed and then ...
The MD5 hash functions as a compact digital fingerprint of a file. As with all such hashing algorithms, there is theoretically an unlimited number of files that will have any given MD5 hash. However, it is very unlikely that any two non-identical files in the real world will have the same MD5 hash, unless they have been specifically created to ...
VirusTotal's Windows Uploader [10] is a discontinued desktop application which integrates into File Explorer's context menu, under Send To > VirusTotal. The application also launches manually for submitting a URL or a program that is currently running in the OS. VirusTotal stores the name and various hashes for each scanned file.
File verification is the process of using an algorithm for verifying the integrity of a computer file, usually by checksum.This can be done by comparing two files bit-by-bit, but requires two copies of the same file, and may miss systematic corruptions which might occur to both files.
In a June 2006 Microsoft report, [2] the company claimed that the tool had removed 16 million instances of malicious software from 5.7 million of 270 million total unique Windows computers since its release in January 2005. The report also stated that, on average, the tool removes malicious software from 1 in every 311 computers on which it runs.
Although the RDS hashset contains some malicious software (such as steganography and hacking tools) it does not contain illicit material (e.g. indecent images). The collection of original software media is maintained in order to provide repeatability of the calculated hash values, ensuring admissibility of this data in court.

In cryptanalysis and computer security, password cracking is the process of guessing passwords [1] protecting a computer system.A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. [2]
