How to remove Dregol Search in Chrome, Firefox and IE

The adware called Dregol is trending on security discussion boards currently, so the article below is going to sort of aggregate the known information about this threat and add in-house research data. The most important part of the present entry is dedicated to the instructions on Dregol removal and ways to restore the system settings that the virus changed.

It doesn’t take a rocket scientist or an IT guru to tell a normal web service enhancement tool from a malicious one. The key differentiation here is in the realm of an app’s activity and symptoms it causes. Normal add-ons won’t make changes to the browser settings unless authorized to do so, whereas adware doesn’t ask the user for approval. The Dregol by Chromium Search extension, for instance, circumvents the user consent phase while drastically modifying the way Chrome, Firefox and Internet Explorer operate on a PC. Likewise, people get this program without really being aware that it’s getting inside, rather than install it voluntarily. This behind-the-scenes installation is powered by a multitude of applications that covertly host the potentially unwanted payload. During the setup of affiliated software, you might actually get a notification about extra promotions, but this information is overlooked by most users because it’s embedded in the default installation options. The types of such underhand shipper programs vary, but in most cases these are free multimedia tools, streaming video downloaders, poorly rated OS maintenance utilities and cracked variants of software updates that are critical for system stability.

  1. The above email address is my work address, my personal email address has too much in it to find a response if sent. I am desperately trying to get rid of “dregol” I uninstalled all downloads of 2015 because it just showed up 2 weeks ago to no avail. I tried to remove it in my add-ons and I cannot get “remove” to happen. Remove is not even a functional choice, it seems to be disabled by this dregol thing. Any additional suggestions? This “dregol” thing is disgusting to say the least! Please help.

  2. Thank you for these easy-to-follow directions! I have no clue how Opera and Dregol appeared on my computer, but I now have them both removed.

  3. hi, whoever the wonderful person is who figured this out —

    both opera and dregol appeared UNinvited on my computer,l and it was making me absolutely crazy until i could get them off. i could probably live with opera (i looked it up), but “dregol” is pernicious.

    thank you so much!

  4. THANK YOU. I installed PDF Merge and Dregol was buried in that install. Following these instructions worked, and I have uninstalled Chrome from my computer so I can install fresh and new. Thanks again.

  5. I changed my opening tab to google as opposed to dregol search.But it wont let me get rid of dregol in manage add ons

  6. I searched around 10 to 15 websites to remove this annoying Dregol search toolbar. Finally this post helped me. I just followed all the points. Hope it doesn’t come again.

    • You’re welcome, John. In regard to prosecuting the bad guys – hopefully, but not very likely. They are using distribution schemes that technically aren’t illicit because users just tend to leave the tricky installation defaults unchanged, thus sort of authorizing the adware to get in.

  7. Thank You!

    This guide was so straight-forward and helpful. I was able to finally get rid of Dregol. It was so annoying

  8. Thank you so much for the straight forward answer. This was one of those rare instances where I didn’t pay attention to what I was installing. Everywhere I checked they were saying add this and run it then install that and run it with these settings, and run this program on a full moon with the lights off and blah blah blah. This was the first one to just point out the simple and direct route. Many thanks!

  9. Also check your registry. I am working on a friends computer, and found it hiding in two places. Also seems to be a part of SuperAntiSpyware. I do not know if this is hidden or an option in installing, as this was already installed on laptop. Just use the edit tab and find, till no more Dregol is found. Hope this helps.

  10. Very helpful for uninstalling from my browsers – but I still can’t uninstall Run_Dregol from my programs. I was wondering if you could help with this too?
