COMPUTER BLOCKED removal instructions

What is COMPUTER BLOCKED?

"COMPUTER BLOCKED" is a fake error message displayed by a malicious website, which users often visit inadvertently - they are redirected by various potentially unwanted programs (PUPs). These applications infiltrate systems without consent (the "bundling" method). PUPs also deliver intrusive online advertisements and continually record various user-system information.

COMPUTER BLOCKED adware

The message states that Windows firewall has detected suspicious activity and, for this reason, the Internet connection has been blocked. To solve this issue, victims must contact "Microsoft's Technical Support" via a telephone number ("+1-844-392-7021") provided. They are then supposedly guided through the recovery procedure. Bear in mind, however, that the "COMPUTER BLOCKED" error is fake and should not be trusted. Criminals attempt to trick victims into calling and paying for services that are not required. Never attempt to call the aforementioned telephone number - you can remove this error simply by closing the web browser. Another downside is display of advertisements. To deliver pop-up, banner, coupon, and other similar ads, PUPs employ a "virtual layer" - a tool that enables placement of third party graphical content on any site. Therefore, delivered ads often conceal underlying content, significantly diminishing the browsing experience. In addition, they often redirect to malicious websites and clicking them can result in high-risk adware or malware infections. Furthermore, PUPs continually gather IP addresses, URLs visited, pages viewed, search queries, and other similar information. There is a high probability that this collected information will contain personal details that PUP developers share with third parties (potentially, cyber criminals) who misuse private data to generate revenue. This behavior might lead to serious privacy issues or even identity theft. Therefore, the presence of a data-tracking app can result in high-risk adware or malware infections.

"COMPUTER BLOCKED" is virtually identical to Suspicious Ransomware Activity, Error Virus - Trojan Backdoor Hijack, Unknown Security Breach, and dozens of other fake errors. All claim that the system is damaged in some way, however, as with COMPUTER BLOCKED, their purpose is simply to generate revenue for the developers by tricking users into paying for so-called 'technical support'. PUPs also have an identical purpose. By offering various 'useful features', they attempt to give the impression of legitimacy. In fact, all are useless for regular users. PUPs cause unwanted redirects, deliver intrusive advertisements, and continually gather various user-system information.

How did adware install on my computer?

PUPs are distributed using a deceptive marketing method called "bundling" - stealth installation of third party software with regular (mostly free) applications. Developers know that users often rush the download/installation processes and skip steps. Therefore, they hide PUPs within the "Custom/Advanced" settings. By carelessly skipping this section, users often expose their systems to risk of various infections and compromise their privacy.

How to avoid installation of potentially unwanted applications?

There are two simple steps you should take to prevent system infiltration by PUPs. Firstly, choose the "Custom/Advanced" settings and carefully analyze each step. Secondly, decline offers to download/install additional applications and cancel those already included. The key to computer safety is caution.
