HDTube: what it is and how to remove it

HDTube is not a virus in the sense of malware that destroys files; our 2014 guide and PCrisk class it as adware, a potentially unwanted program.

It was promoted as a YouTube helper that would improve videos, and the reports describe banner, pop-up and coupon ads, redirects and collection of browsing data. We could not test it in 2026, because we have no copy of the add-on. Treat it as unwanted:

• remove it from every browser
• uninstall anything that came with it
• run a Microsoft Defender full scan and the offline scan

Then change the passwords of accounts you used while it was installed.

Open Chrome, select More (the three dots) > Extensions > Manage extensions, find HDTube and select Remove, then confirm. If the name is not there, look at each extension you do not remember adding, and remove it.

Then clear Cookies and other site data and scan Windows with Microsoft Defender, because a program may add the extension again. If your start page or search engine changed, use Settings > Reset settings; bookmarks and saved passwords stay. Do the same check in Edge and Firefox, as the add-on was written for several browsers.

In Edge, open Settings > Extensions > Manage extensions and select Remove under anything you did not install yourself. In Firefox, open the menu > Add-ons and themes > Extensions, select the three-dot icon of the entry and choose Remove.

In Safari, open Safari > Settings > Extensions, select the extension and click Uninstall. Our 2014 guide listed all of these browsers in its removal part, so check every browser and profile on the PC, and restart the browser afterwards to see that the entry is gone.

No. The adware of this guide is a browser add-on that was promoted as a YouTube helper. Websites that use the name HDTube are different: a search for the bare name today mostly returns adult video websites, and we did not test any of them.

Ads on such a site come from that site and its ad networks, and closing the tab ends them. If the same ads also appear on other sites, look at your extension list and at Installed apps for an add-on you did not choose, and remove it.

Our 2014 guide says adware shows offers of coupons, security tools and Java updates, and that after convincing you that a program is outdated, the ad tries to install another adware program. We could not reproduce the ads in 2026. Do not click them.

The FTC says scammers place bogus ads for software, and advises not to click an ad to download software but to type the address of the site yourself. Update Java or any program from its own menu or from the vendor's website, and check your extension list for HDTube.

Most likely through a free program. PCrisk says the add-on is bundled into the installers used by freeware download sites, and our 2014 guide says it spreads with download managers and PDF creators, or after you are convinced it will improve your browsing.

A rogue website with questionable links is a third route. To find the cause, open Settings > Apps > Installed apps, sort by install date, and look at what appeared on the day the ads began. Next time choose Custom or Advanced in the setup and clear the extras.

We have no evidence that HDTube stole passwords, and we could not test it. PCrisk says it collects browser data, location, IP addresses and unique identifiers, and our 2014 guide says it collects information about your browsing.

An add-on that can read the pages you open can in principle see what you type, so treat the risk as real until the add-on is removed. Remove it, scan the PC, change the passwords of accounts you used while it was installed, and turn on two-factor sign-in. The FTC gives the same steps after malware.

Something else on the PC is adding it again, or you removed it from only one browser. A free program that carried it in may still be installed, and a second browser or profile may still hold a copy.

Open Settings > Apps > Installed apps, sort by install date and uninstall any program you did not choose. Check every browser and profile, run a Microsoft Defender full scan and the offline scan, and look at the extension list again. Our 2014 guide advises to act at once, as waiting brings more ads.

No paid tool is needed. Removal is done by hand: remove the add-on in each browser, uninstall what came with it from Installed apps, and scan with Microsoft Defender, which is built into Windows.

Our 2014 guide recommends an anti-malware program for the job and says it takes a couple of minutes; we cannot promise a time, and we do not claim that any product removes this add-on. If ads remain after the manual steps, run the offline scan, which Microsoft says finds malware that hides while Windows is running, and reset the browser.

Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.

For HDTube, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.

Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
