What is Firewall detecting ‘suspicious’ incoming network connections?
"Firewall detecting ‘suspicious’ incoming network connections" is a fake error message displayed by a rogue website. Users often visit this site inadvertently - they are redirected by various potentially unwanted adware-type programs (PUPs). Note that cyber criminals also promote this scam using Typosquatting - whenever users misspell a URL (for example, "facebook[.]cm" rather than "facebook[.]com") they are redirected to the rogue site. Note also that PUPs deliver various intrusive online advertisements and gather information relating to users' Internet browsing activity.
According to this error message, the system has been infected with a trojan and the activation key has expired. Personal details (banking information, logins/passwords, messages, etc.) are also supposedly at risk. The message goes on to say that malware must be eliminated immediately and users are encouraged to contact Google's Help Desk via a telephone number ("+1-844-284-8623") provided. They then supposedly receive help in resolving this issue. In fact, "Firewall detecting ‘suspicious’ incoming network connections" is fake and has no association with the Google company. Cyber criminals claim to be 'certified technicians' and attempt to scare and trick victims into calling and paying for technical support that is not required. For these reasons, this error should be ignored. You can remove it simply by closing the web browser. As mentioned above, PUPs also generate intrusive advertisements. To achieve this, developers usually employ a "virtual layer" - a tool that enables placement of third party graphical content on any site. Therefore, displayed ads (coupons, banners, pop-ups, etc.) often conceal underlying website content, significantly diminishing the browsing experience. Furthermore, once clicked, these ads might activate a script to downloads/install malware or redirect to malicious websites. Therefore, even accidental clicks can result in high-risk adware or malware infections. PUPs are also record user-system information relating to browsing activity. The list of collected data usually includes (but is not limited to) users' geo-locations, Internet Protocol (IP) addresses, website URLs visited, queries entered into search engines, pages viewed, and mouse/keyboard activity. The collected data may be personally identifiable and shared by PUP developers with third parties (who generate revenue by misusing personal details). Therefore, the presence of data-tracking apps can lead to serious privacy issues or even identity theft.

There are many fake errors similar to "Firewall detecting ‘suspicious’ incoming network connections" (for example, Google Chrome Warning Alert, Suspicious Incoming Network Connections, Error Virus - Trojan Backdoor Hijack, etc.) All claim that the system is damaged or infected, however, as with Firewall detecting ‘suspicious’ incoming network connections, they are designed to trick victims into purchasing unnecessary services. PUPs are designed to generate revenue for the developers. By offering various 'useful features', they attempt to give the impression of legitimacy. In fact, they deliver no value for regular users. PUPs promote various websites (by causing unwanted redirects), deliver intrusive advertisements (using the "Pay Per Click" advertising model), and gather information relating to browsing activity. Most of the promoted websites are fake Internet search engines that also have similar behavior to PUPs - they promote dubious websites, display ads, and record data. These websites are often filled with dozens of intrusive online advertisements. Furthermore, they often generate irrelevant search results that might lead to malicious sites. Therefore, using a fake Internet search engine can result in high-risk adware or malware infections.
How did adware install on my computer?
Most PUPs are distributed via intrusive advertisements or a deceptive marketing method called "bundling" - stealth installation of additional applications with regular (usually free) software. Many users rush the download/installation procedures and skip steps. Aware of this, developers conceal bundled apps within the "Custom/Advanced" settings. Skipping this section often leads to inadvertent installation of various PUPs and compromises users' privacy.
How to avoid installation of potentially unwanted applications?
Be very cautious when browsing the Internet. Select the "Custom/Advanced" settings, carefully analyze each download/installation step, and decline offers to download/install additional software. Furthermore, avoid clicking any advertisements - this might cause various computer infections.
