[13]Unwanted Software Google Blacklist

We frequently [14]clean blacklisted websites and submit reconsideration
requests to have them de-listed. We have encountered many kinds of
blacklist warnings including search engines, anti-virus programs,
firewalls and and e-mail spam.

Recently I came across an interesting case where Google was flagging a
website due to unwanted software. We were able to get to the bottom of
the issue and [15]remove the unwanted malware from the website. In the
process we learned a few things and wanted to share them with you as
well.

Unwanted Software Warning

[16]unwanted-software

Warning for "unwanted software" from Google.

This is a new and uncommon warning issued by Google that was only
recently distinguished from their regular "Malicious Attack Page"
category. It's a bit peculiar because there are no warnings or
notifications in Google search results but it's made quite clear that
something is amiss when you try to visit the domain. In almost all
cases this warning is caused by malvertising: where adware, spyware or
other malware is delivered through third party ads.

Protection from malvertising (and problems associated with unverified
third party content) was a primary reason for the creation of ad
blocking and content filtering software. The danger of malvertising
continues to be a large motivator for the use of ad blocking browser
extensions.

Recovering from Malicious Ad Networks

We started seeing cases of "Unwanted Software" warnings pop up a few
months ago. Almost all of them seemed to be video streaming websites
that used a wide variety of lower quality and cheap advertising
networks.

The solution for these cases is pretty straightforward:
1. Determine all ad networks the affected website is a part of and
check whether or not there have been reported cases of malvertising
on them, then disable those ad networks.
2. In many cases (depending on the ad networks used) it's recommended
to disable all advertisements entirely to get rid of this warning.
3. Be a bit more careful going forward with regard to which scripts
you let run on your domain. Choosing to include third party scripts
on your site is often a risk because you can't ensure their
security.

Unwanted Software With No Ads?

In our reviews however, we noticed something a bit peculiar. While it's
understandable to have a new warning targeting malvertising activities,
what if the website doesn't leverage ads? At first glance it didn't
make sense and naturally we had to investigate to understand why this
would happen.
[17]harmful-programs

Another Google blacklist warning about malicious downloads.

I began working on our customer's website by first checking it out to
see what I was working with. I was specifically interested in the ad
networks it was using. It turns out that the website didn't have ads.

I hadn't seen a case like this before. For those wondering,
malvertisting is exceptionally difficult to troubleshoot because it's
so difficult to detect. The way ad networks work is that they push a
variety of ads to your website at some frequency and it can be very
difficult to find the particular culprit that's presenting the issue.
