How to prevent issues caused by TeamViewer scam?

What is TeamViewer scam?

TeamViewer is a legitimate software used to connect to remote computers, provide remote support, transfer files between different computers and so on. However, there are scammers who use this software for malevolent purposes. In order to trick people into installing TeamViewer scammers often use various scam websites. One of the examples is a tech-support scam page claiming that visitor's computer might be at risk. Very often people do not visit websites of this kind on purpose, they are opened by potentially unwanted applications (PUAs) that are installed on browsers or operating systems.

TeamViewer scam scam

In this case scammers try to trick people into installing TeamViewer through a tech-support scam page that is disguised as an official Microsoft Support page. However, the actual Microsoft company has nothing to do with this scam page. According to this site, the system has detected some unusual activity that might harm a computer and could be used to track financial activities. Visitors are encouraged to report this problem by calling the "+(888) 756-6301" number or/and to allow "technical support" to connect to a computer through TeamViewer. One way or another, scammers use pages of this type to trick people into downloading and installing some computer protection software (packages) that cost from $200 to $1000 or to pay money for their remote support services. It is very likely that they might use TeamViewer (or/and tech-support scam page) to trick people into installing some other unwanted software as well. Note, by allowing scammers to connect to a computer remotely user's risk to get their computers infected with some malware like ransomware. Either way, it is strongly recommended not to trust websites of this type and more importantly, not to allow scammers to connect to a computer through software like TeamViewer. Scams that are designed to trick people into installing TeamViewer can be reported by clicking this link.

Quite often scam pages are opened by installed PUAs. Apps of this type open shady pages, display ads and gather various data. When installed, they often display ads (like coupons, banners, surveys, pop-ups and so on) that, if clicked, open untrustworthy websites or case unwanted downloads or/and installations. They also gather IP addresses, entered search queries, addresses of opened pages, geolocations and so on. People who develop these apps usually share all collected data with other parties who misuse it to generate revenue. Sometimes these parties are various cyber criminals.

What most scams of this type have in common is that scammers use them to trick people into installing paid unwanted software. It is important not to trust these scams and never call the provided numbers (or install offered software). Examples of similar scams are "ERROR # MS-0x8024402C", "HARDDISK_ROOT KIT_TROJAN_HIJACK.EXE" and "Windows Antivirus - Critical Alert". PUAs that open pages of this type usually are advertised as regular, harmless applications. Nevertheless, people who have them installed usually are forced to see unwanted ads and visit untrustworthy websites. besides, developers use these apps to collect various information about their browsing habits.

How did potentially unwanted applications install on my computer?

Potentially unwanted apps usually are downloaded and installed via intrusive (deceptive) ads, or when software developers employ a marketing method called "bundling". They use this method as a way to trick people into downloading and installing PUAs together with other software by hiding them in "Custom", "Advanced" and other similar settings/options of their setups. As a rule, information about additionally included apps is not disclosed properly. However, PUAs cannot be downloaded and/or installed without people giving a permission for that. Typically, they do it unintentionally when they leave all the mentioned settings unchecked and unchanged.

How to avoid installation of potentially unwanted applications?

All software should be downloaded from official (trustworthy) websites. We do not recommend to use third party downloaders (or installers), unofficial websites, Peer-to-Peer networks (like eMule, torrent clients) and other similar channels. If a download or installation setup contains settings like "Custom", "Advanced", they should be checked. In other words, it is not recommended to complete any setup without dismissing offers to download or install unwanted software. Moreover, ads that are displayed on untrustworthy websites, such as gambling, pornography, adult dating and other similar sites redirect to other untrustworthy pages (or lead to unwanted downloads, installations). If a browser opens shady websites or displays intrusive ads, then remove all unwanted extensions, plug-ins or add-ons that are (if are) installed on it. The same should be done with unwanted programs that are installed on the operating system (computer). If your computer is already infected with PUAs, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
