Mod Edit:  PM sent OP requesting RogueKiller log - Hamluis.




I've really appreciate some help with removing what appears to be a ZeroAccess infection, including many tracking cookies and hijacks. These were found by McAfee, MalwareBytes, Microsoft Security Essentials and Rogue Killer.


The symptoms I have encountered are:


  • Windows Security Centre, Firewall, Defender and Windows Updates are all stopped and disabled (checked in services.msc) and cannot be enabled. (Error: 0x80070424)
  • ZeroAccess Trojan appearing in "\AppData\Local\Google\Desktop\Installer" titled 'GoogleUpdate?' with a Unicode heart character.
  • UAC is set to 'Never Notify Me' and cannot be changed.
  • I am unable to download many .exe files in Internet Explorer and Google Chrome. I have been unable to even download the ComboFix setup - which I do not intend to use until advice from this forum. In IE 10 I am presented with the 'This page cannot be displayed' screen, and in Chrome the download fails at 100%.
  • Other issues are constant crashing of the Dell Datasafe Local Backup when the computer is started, and I have problems using the back button in Internet Explorer, which requires multiple clicks before it works.


Here is the most recent MalwareBytes log. Older logs can provided if needed.

Since you have a topic already here: http://www.bleepingcomputer.com/forums/t/547109/suspicious-behaviour-from-mcafee-siteadvisor-and-blocked-firewall/ I'm closing this one pending deletion to avoid potential confusion.
