How to remove Posto.click ads

Posto.click ads show misleading messages about malware infections to make people click on promotional links and purchase software

Posto.click is a website that imitates security software scan processes in order to frighten people and make them believe that their systems are infected with dangerous viruses and other malware. Scammers mimic a well-known vendor's McAfee system scans only to show fake virus infection alerts and then claim that their security software license has expired and needs to be renewed. This is when users are directed to a purchase page, which benefits crooks financially.

McAfee has nothing to do with this ploy, and it is the work of threat actors who seek to benefit from illegal advertisements. If you have been redirected to Posto.click from somewhere else, you should ignore all these fake warnings and check your system using legitimate methods instead – adware^[1] could be behind redirects to malicious sites in the first place.

The site would also ask to enable push notifications, which is yet another way for scammers to insert more ads of low quality. If you have accidentally enabled these, we'll show how to get rid of notifications quickly and easily below.

The fake results

Most commonly, people enter scam websites like Posto.click after being redirected from another suspicious place, such as distributors of cracked software or illegal video streaming. The trick here is for users not to expect this in the first place, which benefits the scam authors in the long run.

After the redirect, people are quickly presented with what looks like a security scan being performed – there are scanned files that are shown, detections, and similar seemingly interactive material. In reality, it is a mere illusion, and it is shown to anyone visiting this malicious website. The results, which are completely bogus, are always identical as well:

Your PC is infected with 5 viruses!

ACTION REQUIRED

Your McAfee Subscription Has Expired!
Renew now to keep your PC protected.
If your PC is unprotected, it is at risk for viruses and other malware.

This message is intended to terrify users and give them the impression that their system is in danger. Fear is a strong emotion that is frequently employed in phishing scams and social engineering^[2] strategies because it impairs people's ability to reason and causes them to make snap decisions.

In practice, no website can check if your system has malware since only a specialized application installed on the system with elevated access is able to accomplish this. Another security advice would be to always confirm that the URL of the website claiming problematic information matches the URL of the firm name shown on the page – Posto.click by no means represents what it tries to portray, and the security vendor has nothing to do with it.

Next steps to take

Increased advertisement quantity, altered homepage, new tab settings, and redirects to questionable websites are all signs that potentially unwanted or dangerous software has been installed. For example, browser hijackers are known to take control of the browser, modify the search engine, and add many sponsored links at the top of the results.

Adware mostly works by sending users to dubious websites, inserting links into fairly unrelated text, displaying pop-up advertisements, and other similar activities that enable those who operate it to make money. Adware's primary flaw is that it prioritizes the display of ads, seldom providing any advantages to users in the process. Additionally, adware could expose them to dangerous material and lead to additional malware/potentially unwanted program installation.

We thus advise you to scan your system for adware even if you don't experience any unusual browser behavior. Running a scan with SpyHunterCombo Cleaner or MalwarebytesMalwarebytes software is the easiest and most efficient way to do this since it can find all the malware-related components and remove them immediately. After that, you need clear the caches^[3] from your browsers and remove any trackers from your computer. You can do this easily and quickly with FortectIntego, while manual methods are also an option.
