"Microsoft Has Detected Some Suspicious Activity" virus removal guide
What is "Microsoft Has Detected Some Suspicious Activity"?
"Microsoft Has Detected Some Suspicious Activity" is malware that locks the computer screen by displaying a fake error message. The software is distributed with a potentially unwanted program (PUP) called TSS MoboPlay - a fake app management tool. As well as promoting "Microsoft Has Detected Some Suspicious Activity", TSS MoboPlay might also gather various user/system information and deliver intrusive advertisements.
"Microsoft Has Detected Some Suspicious Activity" states that the system has been infected and that personal details (emails, logins/passwords, banking details, etc.) are at risk. It is suggested that the infection should be uninstalled immediately by contacting Microsoft certified technicians via the telephone number ("1-800-603-5246") provided. Users are then supposedly guided through the removal process. As mentioned, however, this error message is fake. Criminals generate revenue by tricking victims into calling and paying for services that are not required. Therefore, never trust these people or call the aforementioned telephone number. You can remove the screen lock by entering the "8716098676542789" activation key. TSS MoboPlay might gather various data relating to web browsing activity, including personally identifiable details that are often misused to generate revenue. This behavior can result in serious privacy issues or even identity theft. Another problem is display of intrusive online advertisements. Potentially unwanted programs often employ a 'virtual layer' to generate pop-up, coupon, banner, and other similar ads. The virtual layer enables placement of third party graphical content on any site. The ads often conceal underlying visited website content. In addition, some lead to malicious websites - clicking them is risky and can result in further computer infections. Potentially unwanted programs must be uninstalled immediately.
The Internet is full of fake errors similar to "Microsoft Has Detected Some Suspicious Activity". The list of examples includes (but is not limited to) Your PC Ran Into A Problem, Microsoft Security Essentials Toll Free and Your Windows has been banned. All claim that the system is infected or damaged in other similar ways, however, these errors should never be trusted - they are designed only to generate revenue for the developers by extorting money from unsuspecting users. Furthermore, potentially unwanted programs are often distributed using a deceptive marketing method called "bundling" - stealth installation of third party apps with regular software/apps. Developers know that most users do not express enough caution during the download and installation processes (they rush and skip these procedures) and, therefore, bundled apps are hidden within the this section. Users who carelessly rush and skip steps often inadvertently install rogue applications. Therefore, never rush the download and installation processes. Select the "Custom/Advanced" settings, carefully analyze each step, and cancel all additionally-included programs.
