"Microsoft Support" removal instructions
What is "Microsoft Support"?
"Microsoft Support" is another fake error similar to "Microsoft Security Tollfree", "We Couldn't Activate Windows", "WARNING! 41 Threats Found!!!", and many others. Generally, this error is delivered by deceptive sites that visitors arrive at inadvertently - they are redirected by unwanted apps or intrusive ads. Most potentially unwanted applications (PUAs) infiltrate systems without permission. As well as causing redirects, these rogue apps deliver intrusive advertisements and gather information relating to browsing activity.
This error message essentially states that the system is blocked for the following reasons: the Windows registration key is illegal; the system is using pirated software; the computer is proliferating viruses, and; the system is being used from an undefined location or has been hacked. Users are encouraged to immediately contact 'tech support' via a telephone number ("+1-877-286-9666") provided. Certified technicians then supposedly help victims resolve all issues. This is a scam and Microsoft is certainly not responsible. In fact, criminals claim to be tech support employees and attempt to trick users into paying for services that are not needed (the computers are often safe and virus-free). Therefore, never attempt to call the aforementioned telephone number. Ignore the "Microsoft Support" error. It can be removed by leaving the deceptive websites, however, some use scripts that disable closing of browsing tabs/windows. In these cases, terminate the browser using Task Manager or simply reboot the system. After reopening the browser, do not restore the previous session, otherwise the deceptive sites will also be reopened.
Potentially unwanted apps deliver various intrusive advertisements. To achieve this, developers employ tools that enable placement of third party graphical content on any site. Therefore, the ads often conceal underlying content, thereby diminishing the browsing experience. In addition, clicking intrusive ads can result in various system infections, since some redirect to malicious websites and execute scripts designed to download/install malware. Potentially unwanted apps are also notorious for data tracking. Most record information such as IP addresses, website URLs visited, pages viewed, search queries, etc. Furthermore, collected data usually includes personal details that developers share with third parties. Thus, the presence of information-tracking apps might result in serious privacy issues or even identity theft. You are advised to uninstall all unwanted apps immediately.

As mentioned, "Microsoft Support" shares many similarities with dozens of other fake errors. All claim that the system is damaged, however, these claims are merely attempts to extort money from unsuspecting users. Potentially unwanted applications are all very similar. Most claim to enable "useful features". In fact, these claims are false - potentially unwanted applications usually have just one purpose: to generate revenue for the developers. Rather than enabling the features promised, PUAs cause unwanted redirects, gather information, and deliver ads.
How did potentially unwanted applications install on my computer?
Most unwanted apps infiltrate systems without permission, since developers proliferate them using intrusive advertising and "bundling" methods (installation of third party apps with regular software). Developers do not adequately disclose installation of rogue applications and hide them within "Custom/Advanced" settings (or other sections) of the download/installation processes. Furthermore, many users often rush these procedures, skip steps, and click various advertisements without understanding the possible consequences. This behavior leads to inadvertent installation of rogue apps.
How to avoid installation of potentially unwanted applications?
Lack of knowledge and careless behavior are the main reasons for computer infections. The key to computer safety is caution. Therefore, pay attention when browsing the internet and downloading/installing software. Analyze all steps of the download/installation processes and opt-out of additionally-included programs. Never use third party download/installation tools, since most are monetized by promoting ("bundling") apps. Software should be downloaded from official sources only, using direct download links. Intrusive ads may seem legitimate, but they redirect to dubious websites. If you experience suspicious redirects, uninstall all dubious applications and browser plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
