I assume that you disabled all anti-virus and anti-spyware applications before running Combofix ?
Yes, I even tried booting into safe mode and disabling any services/startups related to the AV currently installed (Avira & MABM). Tried running Defogger. Made sure Combofix.exe program was run off the desktop.
Current state of play:
1) Links in google are not currently arriving at the wrong web page. I'll try to test this more extensively.
2) Google search is acting weird. When I type my search words and press enter or click the search button sometimes it does nothing. It especially doesn't seem to like the enter key. Yahoo search works fine.
3) If I click a link in google search results, then go back to the search results, when I hover the visited link in search results page I see weird indirect links through doubleclick.net. I can't recall seeing this behaviour before e.g.
http://googleads.g.doubleclick.net/pagead/nclk?sa=L&ai=1&u=http://www.virtuallythere.com/On the other computer which I'm using to type this note I get similar but different behaviour. The prefix on the link starts "
http://www.google.com.au" i.e not via doubleclick
Further weirdness: On the infected computer I get the same result searching google.com and google.com.au
On this computer I'm typing on which I'm starting to be less confident about, the link swapping behaviour seemingly only happens if I use google.com.au.
