Zenit 11, Helios 44m - need help!

[anaxorae]

Hello there! I recently got a Zenit 11 with a 44m Helios lens so I was very excited to see what it has to offer. Today I scaned the film and I was disappointed to see that there is a form of lens flare on basically each and every picture, depending on how much light it was when I took the picture, the flare would be bigger or larger. Can you help me if you know why this happens and what I should do differently to get rid of this?

Thank you very much!

Looks like light leaks to me. Check the shutter curtains for pinholes.
