Hello, recently my malwarebytes detected a spyware.zbot on a startup file and doesn't matter what I try to do, I cant manage to remove it. The zbot is moved to quarantine but every time I run a new scan it is found again, and it is sent ot the quarantine again. Could someone help me please? Ah, and malwarebytes doesn't show anything when I do a normal "Threat Scan", it finds when I do a custom scan and check all my drivers and "Scan for rootkits". Addition.txt FRST.txt Report.txt
