TheAdBlock is an adware-supported plugin created and developed by WebPick Internet Holdings Ltd. Adware-laced applications such as TheAdBlock is a Chrome extension that, while claiming to block advertisements, delivers additional ones to your browser. Since TheAdBlock's advertisements may cause performance or security issues, you usually should consider deleting TheAdBlock whenever its services are undesirable. Due to issues with TheAdBlock's chosen installation format and its included uninstaller, malware experts advise using dedicated anti-adware solutions for removing TheAdBlock from Chrome as efficiently as possible.

When Ad Blockers Deliver Advertisements of Their Own

Similar in branding to Vid Adblock, TheAdBlock is adware that claims to be able to block advertising content on your browser, but, in reality, modifies your browser to deliver new advertisements. Currently, malware experts only have seen TheAdBlock being installed in the Chrome browser, although others are just as vulnerable to virtually identical applications. Standard TheAdBlock installations have historically occurred automatically.

TheAdBlock may install itself in bundles with other, freely downloadable applications, via torrents and freeware websites. After doing so, TheAdBlock modifies the Chrome browser for the purpose of generating new advertising content. These advertisements may deliver themselves as:

  • Pop-up windows that launch automatically.
  • 'Sponsored' links or search results.
  • Banners and other graphical elements injected into the Web page separately from its default content.

TheAdBlock isn't threatening (such as a Trojan), but some PC security products may mistakenly identify TheAdBlock as harmful software. Most anti-adware and anti-malware products that detect TheAdBlock also recognize it as a probable variant of Win32/Adware.MultiPlug, an adware program that previously has been a development platform for other adware extensions.

Blocking the Advertisements that Came with the Blocker

TheAdBlock claims to be a reputable browser add-on and even includes a personalized uninstaller utility. However, malware experts found TheAdBlock's bundled uninstaller to be unreliable, resulting in TheAdBlock often failing to remove itself from the modified browser. Standard software uninstall techniques also may lead to TheAdBlock's settings changes remaining untouched, letting Chrome display TheAdBlock's advertisements, even if you have expunged all other signs of TheAdBlock's presence. As per usual, specialized anti-adware products remain the most expedient solution for deleting TheAdBlock, and also may identify the bundles that may install TheAdBlock originally.

TheAdBlock is best noted as a continuation of the general trends of adware programs to distribute themselves automatically. Download sites with adware-bundled links, illicit torrents and other, equally poor reputation download resources are the most common, but not necessarily exclusive means of contact with this unwanted software. Since extensive contact with TheAdBlock advertisements and similar content may be a heavily-trafficked avenue for unsafe contact with online tactics and other attacks, prevention is clearly the ideal solution for any Chrome user.

Examples of some of the aliases your security programs may identify TheAdBlock extensions under include: Win.Adware.Mplug-52, Trojan.Win32.Generic!BT, TROJ_GEN.R047H05HE14 and BehavesLike.Win32.Downloader.fc.
