Malware shows integrated ads on any site with product srch results (Chrome only)

Viruses and worms

I was on IKEA.com and clicked on a link, when all of a sudden Avast intercepted harmful code, which I found was weird.

Turns out, that for some reason Chrome inserts third-party ads above my search results after some 10 seconds. It shows in small letters “ads not by this site”. The items advertised for are not unrelated to the search results (e.g. furniture ads on IKEA.com) but the links go to results.premium-display.com and apparently include malicious software some way or another. Apart from IKEA, I tried a second-hand marketplace and the same thing happens after some 10 seconds.

The first thing I do, of course, is to check my Chrome add-ons. Nothing there, however.

I’ve never seen this thing before. And inserting search results right above the search results of “any” page, sounds quite advanced. How do I get rid of this thing? I seem to have it only in Chrome.
I’d better start checking my Windows registry, but thought it’d be interesting to report this right away…

Seems to have been resolved (“hat sich erledigt”) using ADWCleaner (though the link on the “logs to assist” page led to a seemingly older version of ADWCleaner than on the picture). Thanks for the tip.

The new Version was removed for bug fix.... should soon be back

You’re welcome.

With version 3.000 it also found C:\Windows\System32\Tasks\BrowserProtect.

Most of this is from an infection that I had in April, but which I thought had been removed. And then suddenly four months later, it got reactivated with new unseen behaviour (the ads), which disappeared after removal of the mentioned stuff (including the Freecorder Chrome extension, which probably started it all…)
