Written by Tomas Meskauskas on
What kind of software is Post and Search?
Our research team discovered the Post and Search browser extension during a routine investigation of dubious websites. After we analyzed this extension, we determined that it is a browser hijacker. Post and Search makes modifications to browser settings in order to cause redirects to the find.tnav-now.com fake search engine.
Post and Search browser hijacker overview
Browser-hijacking software promotes websites by assigning them as browsers' default search engines, homepages, and new tab/window URLs. Post and Search behaves in this manner as well. With this extension installed: new browser tabs/windows opened and search queries typed into the URL bar – result in redirects to the find.tnav-now.com site.
It is noteworthy that software within the browser hijacker classification commonly use persistence-ensuring techniques to prevent browser recovery.
Fake search engines usually cannot generate search results, so they redirect to legitimate ones. Find.tnav-now.com redirected to the Bing search engine (bing.com) at the time of research. Keep in mind that this site could lead elsewhere since redirects may be impacted by factors like user geolocation.
Furthermore, Post and Search spies on users' browsing activity. Targeted data may include: visited URLs, viewed pages, searched queries, frequently visited website lists, IP addresses (geolocations), account log-in credentials, personally identifiable details, finance-related information, and so forth. The collected data can be monetized via sale to third-parties.
To summarize, the presence of browser-hijacking software like Post and Search on devices may result in system infections, serious privacy issues, financial losses, and even identity theft.

Browser hijacker examples
We have analyzed thousands of browser hijackers; Galaxy Search, Currency Helper, and Ultimate Basketball Fan Extension are just a couple of examples. This software usually appears legitimate and harmless. Users are enticed with a broad range of useful and advantageous functionalities. However, these functions seldom work as promised, and in most cases – they are utterly nonoperational.
It must be emphasized that even if a piece of software works as indicated by its promotional material – that is not definitive proof of either legitimacy or safety.
How did Post and Search install on my computer?
We acquired Post and Search from its "official" download webpage. Aside from various promotional pages, browser hijackers are endorsed on scam websites. Users primarily access such webpages via redirects caused by sites employing rogue advertising networks, mistyped URLs, spam browser notifications, intrusive ads, or installed adware.
Browser-hijacking software can also be bundled with ordinary programs. The risk of inadvertently permitting bundled content into the system is increased by downloading from dubious sources (e.g., freeware and third-party sites, Peer-to-Peer sharing networks, etc.) and by rushing through installation processes (e.g., ignoring terms, skipping steps, using "Easy/Quick" settings, etc.).
Intrusive adverts proliferate browser hijackers as well. When clicked on, some of these advertisements can execute scripts to perform downloads/installations without user permission.
How to avoid installation of browser hijackers?
We strongly recommend researching software and downloading it only from official/verified channels. Furthermore, installation processes must be treated with care, e.g., by reading terms, studying possible options, using the "Custom/Advanced" settings, and opting out of all additional applications, extensions, tools, etc.
Another recommendation is to be cautious while browsing since fraudulent and dangerous online content typically appears legitimate and innocuous. For example, intrusive adverts may look harmless yet redirect to highly questionable websites (e.g., gambling, pornography, adult dating, etc.).
In case of continuous encounters with ads/redirects of this kind, check the device and immediately remove all suspect apps and browser extensions/plug-ins. If your computer is already infected with Post and Search, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
