@Eddy: Thanks for your advice. I run a bootscan with avast and run Malwarebytes but the threat was still there. I read the other posts before creating this one and they always suggest to start a new post. that is why I opened a new post

@magna86: I run OTL with the script you gave me and also I run the TDSSkiller. the TDSSkiller didn’t find anything.
I am sending the two logs. It seems the problem is solved until now.

should I check something more? should I delete any of the software I’ve installed?

Thanks,
