What is "Your PC is infected with 5 viruses"?

This is a deceptive website disguised as the Update & Security settings in the Windows 10 operating system. The main purpose of this web page is to trick visitors into downloading and installing the OneSafe PC Cleaner program. We advise against installing software that is distributed through, or advertised on, unofficial and deceptive websites such as this. Do no trust any virus/error notifications (or others) displayed on sites of this kind - they are fake.

Your PC is infected with 5 viruses scam

According to this deceptive website, the computer is infected with five viruses. It urges visitors to install an antivirus update immediately, otherwise the viruses will damage the operating system (cause loss of apps, photos and other files). Once the "Install Update" button is clicked, this page displays a pop-up disguised as a system window and states that the antivirus update is prepared and can be downloaded by clicking the "Download Update" button. This button leads to a download page of the OneSafe PC Cleaner program. This program is not a Windows Update or security suite. Do not trust this scam website or download anything from it. Programs that are promoted through deceptive wen pages such as this can never be trusted. Furthermore, it is possible that these sites might be used to proliferate malware.

People often arrive at deceptive, and other untrustworthy websites, due to potentially unwanted applications (PUAs) installed on the browser, or the computer opens them. There are also other problems with these apps. PUAs commonly gather information such as IP addresses, geolocations, addresses of visited pages, entered search queries, and other details relating to users' browsing habits. The developers usually share the data with third parties who might be cyber criminals and misuse it to generate revenue. PUAs often serve unwanted, deceptive ads. When clicked, these open dubious websites or run scripts designed to download or install unwanted, potentially malicious apps. Some examples of ads that PUAs display include coupons, banners, pop-ups and surveys.

This is not the only rogue website used to advertise dubious software in a deceptive way. More examples are "E.tre456_worm_Windows", "VIRAL ALARM OF MICROSOFT" and "Windows is not activated". In most cases, scammers behind these pages attempt to trick people into installing dubious software, however, many similar pages are used to extort money from unsuspecting visitors by urging them to purchase software or pay for services. In any case, never trust websites of this kind and simply close them.

How did potentially unwanted applications install on my computer?

Most people download and install potentially unwanted apps unintentionally. Typically, this happens when the apps are included into the set-ups of other software. Offers to download and/or install them are usually hidden in "Custom", "Advanced" and other similar settings of the download and installation set-ups. This distribution method of unwanted apps is called "bundling", however, it works only when people leave all of the aforementioned settings unchanged - in this way, they inadvertently allow additional apps to be downloaded/installed with other software. Sometimes PUAs can be downloaded and/or installed through deceptive ads - the ads run certain scripts that download/install PUAs (but this can only happen if the ads are clicked).

How to avoid installation of potentially unwanted applications

Use only trustworthy and official websites when downloading software or files. Do not trust third party downloaders, installers, torrent clients, eMule and other Peer-to-Peer networks, unofficial websites, or other download or installation sources/tools. If a setup contains settings such as "Custom", "Advanced", they should be checked carefully. Decline any offers to download or install unwanted apps. Avoid clicking intrusive ads, especially if they are displayed on dubious sites. Frequently, these ads redirect users to other untrustworthy, malicious websites. In some cases, clicking them leads to unwanted downloads and installations. If unwanted ads appear, or unwanted redirects happen regularly, remove all unwanted plug-ins, add-ons and extensions that are installed on the browser, and programs of this kind that are installed on the computer. Check if this problem is then resolved. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
