Rootkit.MBR.Zeghost.J (Boot image)

Hello everybody, I got infected few days ago by a malware that stole most of my password…
I did a factory reset, but after 3 different scan from Avast (paid version) bitdefenser and malwarebytrs I find out I have this Rootkit in the system. I did everything the antivirus suggested and now no antivirus detect anything, BUT my internet connection still act pretty weird, sometimes cut me access to basic website like google or others…
What should I do?
Please I’m Soo desperate.. I’m working everyday on my computer and I’m broke… Really really bad situation…

Hope there is a hero somewhere around here…

Adrien
