Your Computer Is In Blocked State Scam
Written by Tomas Meskauskas on (updated)
What is Your Computer Is In Blocked State?
"Your Computer Is In Blocked State" is a fake error message displayed by a malicious website that users often visit inadvertently - they are automatically redirected by various potentially unwanted programs (PUPs). These apps infiltrate systems without permission (the "bundling" method).
As well as causing unwanted redirects, PUPs deliver intrusive online advertisements and continually record various user-system information.
This error message states that the system is in a blocked state and, therefore, victims must immediately call Microsoft technical support via a telephone number ("1-800-490-5352") provided. They then supposedly receive help in solving the problem.
Bear in mind, however, that the "Your Computer Is In Blocked State" error is fake and simply an attempt to scare and trick users into calling and paying for technical services that are not needed. Never attempt to call the aforementioned telephone number. Potentially unwanted programs employ a "virtual layer" to generate pop-up, coupons, banner, and other similar advertisements.
This is a tool that enables placement of third party graphical content on any site. Therefore, displayed ads often conceal unwanted underlying content, significantly diminishing Internet browsing experience. In addition, These ads might lead to malicious websites and even accidental clicks can result in high-risk adware or malware infections.
In addition, PUPs continually record various user-system information that might contain personal details. The list of recorded data types includes (but is not limited to) Internet Protocol (IP) addresses, geo-locations, website URLs visited, pages viewed, search queries, and mouse/keyboard activity.
This information is later shared with third parties who misuse private details to generate revenue. Therefore, information tracking can result in serious privacy issues or even identity theft. PUPs should be uninstalled immediately.

How did adware install on my computer?
As mentioned above, PUPs are distributed using a deceptive marketing method called "bundling" - stealth installation of third party applications with regular software/apps. Developers know that users often rush the download/installation processes and skip steps.
Therefore, they hide bundled programs within the "Custom/Advanced" settings. Carelessly skipping this section often leads to inadvertent installation of potentially unwanted programs.
How to avoid installation of potentially unwanted applications?
To prevent system infiltration by PUPs, be very cautious during the download/installation processes. Closely analyze each download/installation step using the "Custom" or "Advanced" settings. Furthermore, cancel all additionally-included programs and decline offers to download/install.
