Microsoft Security Tollfree removal instructions
What is Microsoft Security Tollfree?
In most cases, the "Microsoft Security Tollfree" fake virus alert message appears when users end up visiting deceptive/untrustworthy websites. Potentially unwanted applications (PUAs) often force users to visit these websites. PUAs are usually installed without users' knowledge, cause redirects, collect data, and deliver intrusive advertisements. There are plenty of scams similar to "Microsoft Security Tollfree". Some examples are We Couldn't Activate Windows, Your System Data Has Been Compromized, and Windows Support Alert.
Once a deceptive website is visited, it asks users for permission to download multiple files. Do not give permission. Click "Block" or another similar button. The website also displays a message stating that the computer is blocked and that Microsoft itself urges you to do not restart your computer or close the opened window. It states that your computer registration key is blocked. It explains that this might have happened due to one of the following reasons: the Windows registration key is illegal; the opened window is using pirated software; the window is proliferating viruses; the window is hacked or is being used from undefined location. According to scammers, the computer is blocked for your security and you should contact Microsoft Security support team via the telephone number "+1-844-391-8111" provided. These statements are false. Your computer is not blocked and Windows is not using an illegal key. "Microsoft Security Tollfree" has nothing to do with Microsoft - it is a scam used to trick users into purchasing products or services that will supposedly solve the problem (unblock your computer, remove viruses, activate Windows, and so on). You are strongly advised to ignore all requests made by these scammers and to simply close the opened window. If the website prevents you from closing it (a particular script is used), then restart your computer and do not restore the previous session (this opens identical deceptive websites or the websites that led you there).
As we mentioned in our introduction, potentially unwanted applications (PUAs) often redirect users to untrustworthy websites, including those containing fake messages. Furthermore, PUAs deliver intrusive ads (pop-ups, banners, coupons, surveys, etc.) that are displayed through tools that enable placement of third party graphical content on any site and conceal underlying content. These are annoying, but can also lead to untrustworthy websites and even execute scripts that download and install other PUAs. These unwanted apps collect IP addresses, keystrokes, URLs of visited websites, search queries, geo-locations, and other data that might include personal or sensitive details. Information is shared with third parties (potentially cyber criminals) who misuse it to generate revenue. These actions might cause privacy/browsing safety problems or even result in identity theft. We strongly recommend that you uninstall all PUAs immediately.

Many scammers use various fake messages (support alerts, viruses, errors, and so on) to trick users into paying for services or products that they do not need. Most of these scams are very similar - they display fake messages stating that the system is infiltrated by a virus infection, the computer is blocked, users' data is in danger, etc. Most PUAs that cause visits to these websites are also very similar - they generate revenue for their developers by collecting and sharing data, delivering intrusive ads, and causing unwanted redirects. As a rule, PUAs are promoted as 'useful apps', however, few provide the functionality promised.
How did potentially unwanted applications install on my computer?
PUAs are often installed without users' knowledge. Users install them through clicked intrusive advertisements or when software developers use a deceptive marketing method called "bundling" - stealth installation of potentially unwanted applications or other software with regular third party software. Developers avoid disclosing information about the presence of bundled applications and hide them in "Advanced", "Custom" and other options/settings of the installation processes. Frequently, PUAs are installed when users install software without checking additional options/settings or clicking intrusive ads.
How to avoid installation of potentially unwanted applications?
Avoid downloading software from untrustworthy/unofficial sources, or using torrents or third party software downloaders. Use direct links, official and trustworthy websites only. Do not to skip installation steps without checking "Custom", "Advanced" and other similar settings or options. Opt-out of any additionally-included/bundled software, and only then proceed to the next step or finish the installation. Cyber criminals invest many resources into intrusive ad design, and so it is often difficult to determine which are legitimate. Untrustworthy intrusive ads usually redirect to untrustworthy/potentially malicious websites (such as gambling, pornography, adult dating, and so on). If you encounter these advertisements, check installed applications (extensions, add-ons, and plug-ins) on your browser and remove any unknown/unwanted entries immediately. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
