"Activate your Windows now" removal instructions
What is "Activate your Windows now"?
"Activate your Windows now" is just one of many fake messages displayed on various deceptive websites. In this case, it is a fake Windows Security alert message. Generally, people do not visit these deceptive and untrustworthy websites intentionally - they are redirected to them by potentially unwanted applications (PUAs). Typically, PUAs deliver intrusive ads and record data. Most users install these unwanted apps inadvertently.
According to scammers who designed the "Activate your Windows now" fake security alert (the fake message in the Windows Security pop-up window), the computer is blocked due to a 'system warning' state. Users are urged not to restart their computers or press any keys. Scammers attempt to trick users into contacting "certified technicians" via the telephone number (+1-877-220-4850). They state that users must contact them to remove the "critical infection" - to resolve the problem that has supposedly affected the operating system. Scammers behind the "Activate your Windows now" scam claim to be technicians (supposedly representatives of Microsoft), making the message seem like a legitimate security warning from Windows (they display a system information window). They also attempt to trick people into believing that their Windows Operating Systems are not activated. Note that the pop-up window also contains "User name" and "Password" fields that must be completed. In this way, criminals attempt to acquire users' account credentials. Do not enter any details. Note that system warning information can be accessed only by the Windows Operating System, and not via any website. These fake alerts are used by scammers to trick people into contacting them and paying for services (provided by "certified technicians") or purchasing software. Generally, scammers design these deceptive websites only to generate revenue by making users believe that there is a problem with their computers (that are apparently infected with viruses, and so on). These fake messages should never be trusted. We recommend that you simply close the website that triggered the "Activate your Windows now" fake security warning. If it prevents you from closing it, use Task Manager and terminate the entire browser process or simply restart your computer. Do not return to this website or restore the previous session.
As mentioned in our introduction, potentially unwanted applications cause redirects to deceptive websites that display fake messages such as "Activate your Windows now". These unwanted apps also deliver intrusive ads and gather data. They trigger ads displayed using tools that enable placement of third party graphical content on any site. Therefore, they conceal underlying content of any visited website. Do not click them, since they often redirect users to untrustworthy websites. Some might execute scripts that download/install other unwanted apps. Thus, clicking intrusive ads can lead to various system infections. Furthermore, PUAs collect data relating to browsing activity such as IP addresses, search queries, geo-locations, URLs of visited websites, and personal/sensitive details. Developers share the data with third parties (potentially, cyber criminals) who misuse it to generate revenue. Thus, having these apps installed might lead to privacy/browsing safety issues or even identity theft.

There are many examples of fake messages that are similar to "Activate your Windows now", such as This Computer Is Blocked, MS MALWARE ALERT, Your Computer Was Locked, and so on. The main purpose of these deceptive websites is to trick people into contacting scammers who try to extort money from people by urging them to purchase software products or online technical services. All PUAs are similar - developers promote them as 'useful' and legitimate tools. In this way, they trick people into downloading them. In fact, these apps provide none of the functionality promised. They are designed only to generate revenue for the developers and simply cause problems rather than giving any real value.
How did potentially unwanted applications install on my computer?
Some potentially unwanted applications have official websites, however, most users install them inadvertently by clicking untrustworthy, deceptive ads or when software developers use "bundling", a deceptive marketing method used by software developers to trick users into downloading/installing potentially unwanted applications together with other software. Developers do not disclose information about the presence of unwanted apps in installation/download set-ups and hide them in "Custom"/"Advanced" options/settings. Furthermore, many users skip download/installation steps without checking settings, thus leading to PUA installations.
How to avoid installation of potentially unwanted applications?
Avoid downloading software from untrustworthy and unofficial sources, using third party software downloaders, and so on. Use direct links, and official and trustworthy websites. Never skip download/installation steps without checking the "Custom", "Advanced" and other similar settings or options. Deselect additionally-included, unwanted software, and only then proceed to the next step or finish the process. Many untrustworthy intrusive ads redirect users to dubious and potentially malicious websites (gambling, pornography, adult dating, and so on). If you encounter these advertisements (or redirects caused by them), check installed applications (extensions, add-ons, and plug-ins) on your browser and remove any unknown/unwanted entries immediately. Also check the list of installed programs on your computer (operating system). If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
