How to remove TechSignalSearch from Mac computers

What is TechSignalSearch?

TechSignalSearch is the name of malicious software that causes a number of problems. Research shows that most people who have systems and/or browsers infected with TechSignalSearch do not know exactly how this malicious software was downloaded and installed. This software prevents apps from functioning, forces browsers to open various websites, causes problems with internet connections, and so on. It might also monitor web browsing activity. If there is reason to believe that TechSignalSearch is installed on the operating system and/or browser, remove it immediately.

TechSignalSearch adware

People with TechSignalSearch installed on their systems experience problems with internet connections and cannot properly use some applications. For instance, this malicious software stops Safari and Mail apps from responding, does not allow email and other clients/browsers to establish a connection to the server, reduces internet speed, and so on. Some users are also forced to search using the Yahoo search engine, although their default search engine is set to Google. TechSignalSearch is likely to gather various browsing data. For example, IP addresses, geolocations, addresses of visited websites, entered search queries, and so on. It might also record private, sensitive information. If this is the case, developers might misuse the information to generate revenue and/or sell it to third parties (potentially, cyber criminals). To avoid problems caused by TechSignalSearch, remove it immediately.

People download and install software such as TechSignalSearch intentionally - they often believe that it is legitimate and useful (developers advertise it as such). They are generally tricked into installing it. These apps deliver no real value and are designed only to generate revenue for the developers. Furthermore, they often cause problems relating to browsing safety and privacy, and users sometimes experience more serious problems such as identity theft, monetary loss, etc.

How did potentially unwanted applications install on my computer?

In most cases, malware and other unwanted software is distributed through Trojans, spam campaigns, fake software updaters, software 'cracking' tools and dubious software download sources. Trojans are malicious programs that often cause chain infections. In summary, when a Trojan is installed, it starts proliferating other malicious programs. To distribute unwanted software through spam campaigns, cyber criminals send emails with malicious files attached (or web links that download malicious files). Operating systems become infected when people open the files. Typically, attached files are Microsoft Office or PDF documents, archive files (ZIP, RAR), executable files (.exe and other files), JavaScript files, so on. Fake software updating tools install malicious software by exploiting bugs/flaws of outdated software that is installed on the computer, or by installing unwanted software rather than updates, fixes, etc. Software 'cracking' tools infect systems in a similar manner. People who use these tools expect them to bypass activation of licensed, paid software, however, they often install malware or other unwanted programs instead. Untrustworthy, unofficial websites, free file hosting, freeware download websites, third party downloaders, Peer-to-Peer networks and other similar software download channels are used to proliferate malicious programs. Cyber criminals upload malicious files that they disguise as legitimate and harmless, and hope that someone will download and open them. When executed, the files download unwanted software, including malware.

How to avoid installation of potentially unwanted applications

Do not open attachments or web links that are included in irrelevant emails, especially if they are received from unknown, suspicious addresses. Installed software should be updated through implemented tools and/or functions that are designed by official developers. Files and software should be downloaded from official, trustworthy websites. None of the tools mentioned above should be trusted. If installed software is not free, it should not be activated using unofficial, third party activation ('cracking') tools. It is illegal to activate licensed programs in this way, and these tools can infect systems with malicious programs. Scan the operating system with reputable antivirus or anti-spyware software regularly and keep it up to date. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
