Tech Support scammers rip big brand security software with fake warnings

Just when we thought we had seen it all, scammers come out with an elaborate and clever scheme to trick users into calling for bogus tech support. If you are looking to download one of the popular antivirus or anti-malware product on the market, watch out before you click.

Lookalike pages

Fraudsters have set up fake download pages that look incredibly like the authentic ones. Judge for yourself:

There is even a fake page for our own Malwarebytes:

Except for the toll-free number (which is not ours), the page is pretty much the same as the real one.

Hijacked software

Each page links to a download, which of course is not the actual software but certainly looks like it:


The guys behind this went to such lengths that they actually piggy-backed on the real programs and inserted their own piece of code half way through the installation procedure:

Have a look at how well done it is with this fake Malwarebytes Anti-Malware installer:

Call to action

We are reporting the sites to the registrar and passing on the LogMeIn codes so that interested parties can take appropriate actions.

Cump Tech Media Pvt Ltd |, | 1-855-209-0559  | LogMeIn: 186024

This company has been added to our blacklist.

To avoid these fake installers, users should always go to the company’s official website.

Another thing you can watch for is whether the file has been digitally signed by the vendor or not. This wasn’t the case here and would be a (subtle) giveaway that it is not trustworthy.
