Lenovo G50-70, bios update wrong checksum

Greetings!

I have a Lenovo G50-70 notebook it worked fine so far, but recently I got some UEFI related treat warnings from my antivirus scanner. I'm not sure if its a falsepositive or not since I'm extremely paranoid about security and always make extra precautions to avoid nasty stuff getting on my computers, but just to be safe I wanted to reflash my BIOS.

However when I head to this official download page: 
https://support.lenovo.com/us/en/downloads/DS100522

The BIOS update related cheksums are all wrong for me. The file I download has a completely different set. 
I would be very greatful, if someone could look into this for me. I don't want to end up with a corrupt or tainted update file during the flashing process.

Thank you very much in advance and have a nice day! Smiley Happy
