Bitdefender V10 Update Error

Hi voldor and welcome to BitDefender Support Forum.

The MD5 error appears when:

1) you have a low-speed/unstable internet connection. The update packets might become corrupted.

2) the update server is over-loaded.

3) the update server is in the middle of updating process (new files are uploaded on them), in which case you might download a newer version and an older version of the same file which results in an error.

The solution is simple: either wait a few moments (sometimes the error is gone after a few seconds) and try again an update, either try another update server:

http://upgrade.bitdefender.com (default setting)

http://upgrade1.bitdefender.com

http://upgrade2.bitdefender.com

http://upgrade3.bitdefender.com

http://upgrade4.bitdefender.com

Hello

Do you use a router for your internet connection?

Please reboot and try again. Thank you.
