MS-SYSINFO32 removal instructions

What is MS-SYSINFO32?

"MS-SYSINFO32" is one of many fake virus, alert, error, and other messages that include We Couldn't Activate Windows, Your System Data Has Been Compromized, and Windows Support Alert. These bogus messages usually appear when users visit untrustworthy/deceptive websites, however, they are also caused by potentially unwanted applications (PUAs) that force redirects to them. Generally, users install PUAs inadvertently and, once installed, cause unwanted redirects, deliver ads, and collect data.

MS-SYSINFO32 POP-UP Scam

When opening this deceptive website, a fake warning alert message appears citing a "MS-SYSINFO32" error and stating that the computer is supposedly infected with a pornographic spyware virus. It also states that Facebook logins, credit card details, email logins, and photos and/or documents have been stolen. To prevent any further damage, users are encouraged to contact "expert engineers" within five minutes using a telephone number "+1-(888-726-5133" provided. We strongly recommend that you ignore these warnings and demands. The claims are false - your system has probably not been infected or encountered any genuine errors. Some scammers proliferate these fake warnings/alerts in attempts to trick users into contacting them and paying for services or products to solve 'problems' that do not actually exist. The solution is simple: close the opened window or website and ignore all warnings about what will supposedly happen if you close it. If you cannot close it, use Task Manager to terminate the entire browser process, or restart your computer. Note: do not restore the previous session, since this will reopen the website/s that originally led to this fake warning.

As mentioned above, potentially unwanted applications cause redirects to websites that display fake messages. Furthermore, they also deliver intrusive ads (coupons, banners, surveys, pop-ups, etc.) that are displayed using tools that enable placement of third party graphical content on any site and conceal underlying content. If clicked, these ads might redirect to other untrustworthy (potentially malicious) websites or run scripts that download other PUAs. Another negative aspect of PUAs is information tracking: these apps collect data including IP addresses, URLs of visited websites, keystrokes, geo-locations, search queries, and also personal or sensitive information. These details are then shared with third parties (potentially, cyber criminals) who misuse it to generate revenue. Therefore, having these PUAs installed risks privacy/browsing safety issues or even becoming victims of identity theft. Therefore, uninstall these applications immediately.

Scam messages (fake alert, error, warning, etc.) often trick users into contacting the scammers and paying for products or services that users do not need. Associated PUAs that often lead to these websites are also very similar. Most PUAs are promoted as 'useful', but these are attempts to trick users into downloading and installing them. In most cases, PUAs are designed only to generate revenue by collecting and sharing data, causing unwanted redirects, and delivering advertisements.

How did potentially unwanted applications install on my computer?

Most users install PUAs unintentionally through certain ads that, once clicked, execute scripts designed to download them, or when software developers use a deceptive marketing method called "bundling". Bundling is stealth installation of various PUAs with regular software. In summary, developers hide PUAs in "Custom", "Advanced" and other similar settings of the installation processes. Therefore, information about included PUAs is not properly disclosed, thus making it easier to trick users into installing them. Many users do not check the settings, or simply skip installation steps - in this way, they install PUAs without their knowledge.

How to avoid installation of potentially unwanted applications?

Download software from trustworthy, official sources, and direct links only. Avoid using third party software downloaders, torrents, or other untrustworthy channels. Check all available settings including "Advanced", "Custom" and other sections of the installation dialogs. Do not skip installation steps without declining unwanted offers of additional software (such as potentially unwanted applications). Only then, finish the installation. If you constantly encounter ads that redirect you to dubious websites (adult dating, gambling, pornography, etc.), check your browser for new unknown/unwanted extensions, plug-ins, and add-ons, and unwanted software on your computer. Uninstall all suspicious entries immediately. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
