What is TechSignalSearch?

When you install certain applications using the Default mode, TechSignalSearch may have installed itself without your approval. You might also installed it by downloading attachments from spam emails or clicking pop-up advertisements.

TechSignalSearch

This program affects your browser and computer in a nasty way:
1. It shows paid links and other marketing content that redirect your browser to harmful webpages. If the redirected webpage is controlled by hackers, you might become the victim of a drive-by attack.
2. It can spy on your online activities and collect your browsing history details. Then, it will deliver annoying ads based on your information for profits.
3. It can change your homepage secretively once it finds a way to run its files on your Mac.
4. Last but not least, TechSignalSearch will run automatically at startup every time you turn ON your Mac. The undesired program creates files in system folders that are difficult to access. As long as they are in your macOS, TechSignalSearch may load itself every time the system starts. It is not only a potential threat, but will slow down your Mac as well.

How to avoid installation of unwanted apps

  1. When installing software, choose the custom installation and then check the optional installs. Make sure that you only install the essential ones put the unnecessary ones aside. Take a careful look at Terms and Agreements, do not just scroll down in a few seconds.
  2. Remember not to open attachments (or web links) in a suspicious email, especially when it came from an unknown sender. It is highly possible that hackers use them to trick you to download the malware.
  3. Do not download files or install apps from unsecured websites.
  4. Back up your files regularly, install the latest updates for your Mac, and set up reliable antivirus software to detect and remove malware. At the same time, remember to download antivirus apps only from reputable vendors.
