I have already run dds malwarebytes combofix and other tools before finding this site.
All seem to fix the problem initially but then it comes back. I can load pages normally in firefox but when I get a list of results on google searches, I can click through to the correct page from the search results once or twice, then the redirect starts to happen again generally but not always to ihavenet.com
Following one of the threads here I downloaded and ran frst64
the results are attached.
I have no idea which bits I can safely add to a fix list.
The date of the infection is no earlier than June 15 2013, I think.
Any help greatly appreciated.
