Even I tried many tools. none of them detected. So i felt either it should new signature that none of the BIG anti-virus to small anti-malware can detect it or it should be some script that is used by browser should have been.
Some of the testing I did : [this may help everyone, how to identify the behavior of malware/adware]
1)Pop up occurs very frequently in
2) Pop up never occured in PORN sites
Conclusion : These happened irrespective of incognito mode, So Browser extensions/addons are not culprit. The only thing in common is "Google" Ads. Google never serve ads in PORN site.
Thanks to your tool . Actually, your 2 generated files contains complete info about my system. Upon checking those I came to know some new entries were added in my "C:\Windows\System32\drivers\etc\hosts" file. By default, it will be in "read-only" mode. since i was playing around for some other purpose, i kept it on non read-only mode.
Below entries are newly added in hosts file:
103.50.162.86 pagead2.googlesyndication.com
103.50.162.86 s7.addthis.com
103.50.162.86 contextual.media.net
103.50.162.86 connect.facebook.net
103.50.162.86 s3.buysellads.com
So, in the past 20 days, i was installing many networking or proxy related tools and plugins. One of which might have modified it.
After deleting those unwanted entries, eclkspbn.com pop-ups are not coming. I tested for 1 hr. But not sure it may come again or not. Anyway, I keep any eye on hosts file.
