What is TeamViewer scam?
TeamViewer is legitimate software used to connect to remote computers, provide remote support, transfer files between different computers, and so on, however, scammers use this software for malicious purposes. They often trick people into installing TeamViewer using various scam websites.
One example is a tech-support scam site claiming that the visitor's computer might be at risk. People do not generally visit websites of this kind intentionally - they are opened by potentially unwanted applications (PUAs) installed on browsers and operating systems.
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 web page. Note, however, that Microsoft has nothing to do with this scam site. According to this website, the system has detected 'unusual activity' that might harm the computer and could be used to track financial activities.
Visitors are encouraged to report this problem by calling the "+(888) 756-6301" number and allow "technical support" to connect to the computer through TeamViewer. Scammers use these sites to trick people into downloading and installing computer protection software (packages) that cost in the region of $200 to $1000, or to pay for so-called 'remote support services'.
It is likely that they might also use TeamViewer (and/or a tech-support scam site) to trick people into installing other unwanted software. Note, by allowing scammers to connect to a computer remotely, users risk having their computers infected with malware such as ransomware.
In any case, do not trust these websites, and more importantly, do not allow scammers to connect to your computer through software such as TeamViewer. Scams that trick people into installing TeamViewer can be reported by clicking this link.
Scam pages are often opened by PUAs installed on the system. They can open dubious web pages, display ads, and gather various data. When installed, they often display ads (such as coupons, banners, surveys, pop-ups, and so on). If clicked, these open untrustworthy websites or cause unwanted downloads/installations.
They also record IP addresses, entered search queries, addresses of opened pages, geolocations, and so on. People who develop these apps usually share the data with other parties who misuse it to generate revenue. Sometimes these parties include cyber criminals.

Most of these scams are used to trick people into installing and paying for unwanted software. Do not trust these scams and never call the telephone numbers provided (or install the software offered). Examples of similar scams are "ERROR # MS-0x8024402C", "HARDDISK_ROOT_KIT_TROJAN_HIJACK.EXE", and "Windows Antivirus - Critical Alert".
PUAs that open these pages are usually advertised as regular, harmless applications, however, people who have them installed on their systems are forced to see unwanted ads and visit untrustworthy websites. Furthermore, developers use these apps to collect information relating to users' browsing habits.
How did potentially unwanted applications install on my computer?
PUAs are usually downloaded and installed via intrusive (deceptive) ads or when software developers employ a marketing method called "bundling". They use this method to trick people into downloading and installing PUAs with other software. They hide additional software in "Custom", "Advanced", and other similar settings/options of the set-ups.
Generally, information about additionally-included apps is not properly disclosed, however, PUAs cannot be downloaded or installed without people first giving permission. Typically, they do this unintentionally when they leave settings unchecked and unchanged.
How to avoid installation of potentially unwanted applications?
Software should be downloaded from official (trustworthy) websites. Do not use third party downloaders or installers, unofficial websites, Peer-to-Peer networks (eMule, torrent clients), or other similar channels. If a download or installation setup contains settings such as "Custom", "Advanced", check them thoroughly.
Do not use any setup without dismissing offers to download or install unwanted software. Note that ads that are displayed on untrustworthy websites (such as gambling, pornography, adult dating, and others) redirect to other untrustworthy sites (or lead to unwanted downloads/installations).
If the browser opens dubious websites or displays intrusive ads, uninstall all unwanted extensions, plug-ins, and add-ons. The same applies to unwanted programs installed on the operating system (computer). If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
