Kaspersky AntiVirus 13 download results in file with different MD5 hashes

4 pointsblueplastic12y ago2 comments

I just downloaded a handful of copies of Kaspersky Antivirus 13 via the HTTP link below and keep getting a file with the same name, but a different MD5 hash. Can someone else try downloading the file and checking the hash value for a couple of files to see if this is something Kaspersky is doing? Are they changing the MD5 hash of the file dynamically for each download?

The file name I downloaded is: kav2013_13.0.1.4190abcdefgEN_4519.exe

I was downloading the file from here (expand Kaspersky Anti-Virus under "Personal and Family Security" at the bottom and get the English/USA Canada version): http://usa.kaspersky.com/downloads/product-updates

Does this happen for others?

The MD5 Hash app I'm using: WinMD5Free v1.20 on Win 7

I've done it three times, and get the same hash each time:

  e234d2efd7d7201e4886d2f21a329a3e

I'm using:

  md5sum --version
  md5sum (GNU coreutils) 5.3.0

Edit: On Windows XP

Did this a few times, no change in the hash.

  MD5 (kav2013_13.0.1.4190abcdefgEN_4519.exe) = e234d2efd7d7201e4886d2f21a329a3e
