Google Search asks for a captcha authentication

boyboyds · 20 Aug 2015

Hi,

This has never happened to me before. I was trying to fix a WordPress website (for the very first time), but now every time I Google something using the word "WordPress" I get the following message -

"Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot."

If I search "problem posting WordPress" - I get this message.
If I search "problem posting YouTube" - no message.

What is this......?

Ran Malwarebytes - no issues.

Thanks,
-BBDS

I'd never had such a notification until the last 6 months or year.

Since then, I've noticed it 2 or 3 times; most recently yesterday.

Not clear to me what triggers it as I wasn't doing anything out of the ordinary for me.

I can't get the message :/

Some ISPs tie several dwellings together on one network before there is a connection to the internet. In those cases, Google sees all of those dwellings as "traffic from your computer network". I see this CAPTCHA at work - usually when I use "site:domain.com" in the search.

@TrashZone .... this message only pups up on my PC, my wife's laptop has no issues, though I was first working on that website from her machine and also Googled from her machine for some advise.

This is the first time I dealt with the WordPress, and it is kind of buggy.

Thanks,

Well I had the same problem for the last week or so. Mostly when performing searches like Usernameissues describes.

MBAM scan - clean
Comodo AV scan -clean
Emisisoft Emergency Kit scan - clean

Zemana Antimalware scan - malicious objects detected

Google Search asks for a captcha authentication-zemana-antimalware.jpg

Code:

stflt.sys
Status             : Scanned
Object             : %systemroot%\system32\drivers\stflt.sys
MD5                : B9657A0AFF28C1CB114ACC0CB93EE4BB
Publisher          : Crawler, LLC
Size               : 51496
Version            : 4.0.1.1
Detection          : Win32/Browser.Hijacker.Crawler!Ep
Cleaning Action    : Delete
Traces             :
                File - %systemroot%\system32\drivers\stflt.sys

Since removal I don't see that captcha anymore. I was also seeing a similar captcha on a few occasions using other search engines. Most notably:

zoeken dot nl (dutch)

iZito - English equivalent

I cannot say for sure that removal of the file is the reason why I no longer see the captcha.

Callender,
I don't want to derail this thread, but hopefully the OP won't mind this excursion/rant:

This is what I hate about antivirus apps. Your Comodo app should have flagged this and let you decide if it is a PUP. The file has been listed on VirusTotal for a month now. I know that Comodo uses VirusTotal info, so Comodo knows about that PUP. IMO, antivirus apps should offer a setting that lets users opt to see every possible warning.

BTW, I'm guessing that the file that you had is the same file that I linked to in VirusTotal based on the MD5 info. Odds are, this is not an MD5 collision.

Callender · 21 Aug 2015

Yes Comodo should have picked it up. Not sure why it didn't because it usually alerts on anything suspicious.

It is the same file listed on Virustotal:

From my system image backup.

Comodo re-scan comes up clean!

I suppose I'd better report it!

Okay I've looked into it. Thanks for the post otherwise I probably woul not have gone digging through the settings. It seems that there was a mis-configutation and PUP detection was switched off!
