Hello,
Recently, i've installed electrum wallet on my new computer.
I set my seed and evrything was fine.
My balance was right.
Today i opened my wallet and discovered a transaction that i haven't made.
output : 15puCD3bGbTcX9krmDfPKicoMhAMC4njvh

transaction id : e539ec86e5fbce134cc5c2d6d9f21fd907824b698848bc45d2b5aea08afce279

My balance is now 0

What's wrong

Did i lost evrything ?
Is it dur to vulnerability of the 3.0.5 version ?

I'm really scared

Anybody could help me ?
