Knaws[.]top overview

It must be mentioned that exactly how rogue sites operate (i.e., what they host/promote) might be dictated by the visitor's IP address/ geolocation.

At the time of research, knaws[.]top ran the "Avast - Your PC Is Infected With 5 Viruses!" scam. This deceptive content consists of a fake system scan that "detects" various threats on the visitor's device. It must be stressed that this scam is in no way associated with the Avast Antivirus or its developer – Avast Software s.r.o.

In most cases, scams of this kind are used to endorse untrustworthy or harmful software, e.g., fake anti-virus tools, adware, browser hijackers, PUAs, etc.

Additionally, knaws[.]top requested that the visitor enable its browser notification delivery. If allowed, the webpage will spam the user with advertisements promoting online scams, unreliable/hazardous software, and potential malware.

Browser notification spam in general

We have inspected countless rogue webpages; highpotencyguard[.]com, alltimebestdefender[.]com, and lifepcessentials[.]com are but a couple of examples. These sites deliver browser notifications that predominantly promote deceptive and malicious content.

Note that while legitimate products or services may be encountered via these ads – they are unlikely to be endorsed in this manner by any official parties. It is most probable that this promotion is undertaken by scammers who abuse the content's affiliate programs to obtain illegitimate commissions.

How did knaws[.]top gain permission to deliver spam notifications?

Websites need user consent to display browser notifications. Therefore, if you are receiving these adverts from knaws[.]top – it means that you have likely entered this page at some point and enabled their delivery by selecting "Allow", "Allow Notifications", or an analogous option.

How to prevent deceptive sites from delivering spam notifications?

If you access a suspicious page – do not permit it to deliver browser notifications. In other words, do not click "Allow", "Allow Notifications", or any similar options presented on such sites. Instead, we advise denying notification delivery – i.e., pressing "Block", "Block Notifications", etc. – or ignoring these requests altogether.

Should your browser continuously force-open dubious websites without prompt, it could be due to the presence of advertising-support software (adware) on the device. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
