I am running Windows7 64bit and have been experiencing odd internet access refusals . At first all internet connections worked fine except for those related to Avast antivirus and Comodo Firewall which I run . After a restore reset I found nothing connected except my bank account. I ran Malwarebytes and it cam up with one target: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CryptSvc\Start (Disabled.Cryptsvc) -> Bad: (4) Good: (2) -> Quarantined and deleted successfully Malwarebytes did a successful quarantine operation but found the same result on a rerun . I ran Combofix but still no removal . Can anyone identify this definitely as malware and suggest the next step .
