Similar scam examples

The Internet is rife with deceptive and malicious content. We have investigated thousands of online scams; "Your McAfee Subscription Is Out Of Date", "McAfee - A Virus Has Been Found On Your PC!", and "McAfee - TROJAN_2022 And Other Viruses Detected" are merely a couple examples of ones akin to "TROJAN_2023 And Other Viruses Detected (5)".

It must be stressed that regardless of what a scam warns, offers, or promises – its goal is to gain and subsequently abuse victims' trust. Therefore, we strongly recommend exercising caution while browsing.

How did I open a scam website?

Scam websites are primarily promoted through pages that use rogue advertising networks, misspelled URLs, spam browser notifications, intrusive ads, adware, and spam emails/messages.

To elaborate on some of these, when a user accesses a webpage employing rogue advertising networks, they can be immediately redirected to a deceptive site, or the redirect can occur when hosted content is interacted with (e.g., clicking buttons, text input fields, links, ads, etc.). Adware can display scam-promoting advertisements or force-open websites that host deceptive content.

How to avoid visiting scam websites?

It is crucial to be vigilant while browsing since fake and malicious online content usually appears legitimate and harmless.

We advise against using websites that offer pirated software/media or other questionable services (e.g., Torrenting, illegal streaming/downloading, etc.), as these sites are typically monetized through rogue advertising networks. We recommend paying attention to website URLs and entering them with care.

To avoid receiving unwanted browser notifications – do not permit suspicious pages to deliver them (i.e., do not click "Allow", "Allow Notifications", etc.). Instead, ignore or deny notification requests from such webpages (i.e., select "Block", "Block Notifications", etc.).

We advise against opening the attachments or links found in dubious/irrelevant messages, as they can promote scams or cause system infections.

Additionally, all downloads must be performed from official and verified channels. When installing, it is important to read terms, study possible options, use the "Custom/Advanced" settings, and opt out of all supplements (e.g., apps, extensions, tools, etc.) – to prevent bundled/dangerous content from infiltrating the system.

If your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate all threats.
