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.

Browser shortcuts are also reconfigured to launch the above-mentioned site every time they are triggered. These alterations turn into a messy issue because is going to be visited more often than any other web page on the infected PC, and the user is stuck with these settings because they cannot always be efficiently corrected manually.

The adware’s landing site is intended primarily for displaying ads. Within the results it returns for any given query, there is a big share of sponsored data. Redundancy of those ads above the fold is both a nuisance and a hurdle for normal usage of browsers as the page load time tends to progressively increase.

    Thank you.
    Finally a straightforward help session; especially since I have xp on my home computer.

  2. Kerry Knuckles says:

    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.

  3. Barbara Rice says:

  4. Angelyn Domingo says:

  5. susie margaret says:

    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!

  12. John Barry says:

    Thank you for the clear help. Any chance of prosecuting the dirtbags behind it?

    • admin says:

      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.

  13. Gabriel Huffman says:

  16. Wayne says:

    Thank you! I believe it was helpful! But then again ? time will tell

  17. Edward says:

    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!

    Thank you!!! I tried several removal techniques but yours works!!

  21. microdot says:

    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.

  22. Rach says:

    Yessssss!!! Thank you for the advice.

  23. Sarah Keates says:
