InstallCore is a browser extension classified as a Potentially Unwanted Program by PC security analysts. It functions as a browser hijacker, and there are many unwanted behaviors that InstallCore causes. Some of these may include the following:

  • Irritating, repetitive pop-up advertisements on the affected browser.
  • Web browser redirects to malicious sites that contain suspicious, potentially damaging content.
  • Sudden appearance on the affected Web browser without being installed by the affected computer user.

InstallCore may be bundled with free software, included as a browser plug-in or toolbar that may be installed along with genuine programs unless the computer user explicitly opts out. Unfortunately, it may be difficult to opt out of InstallCore and similar adware during the installation process. In many cases, computer users have to use custom or advanced installation to ensure that only the software they want is installed and that no suspicious programs or unwanted applications like InstallCore are included in the setup.

Many anti-malware programs may not detect InstallCore because it's a low-level threat. Because of this, antivirus programs may not prevent PC users from installing InstallCore. In many cases, computer users may not realize there is a problem until their Web browser starts bombarding them with advertisements and redirecting them to low-quality websites. Although some computer users may find InstallCore useful, any benefit that may be derived from using this PUP is outweighed by the many unwanted behaviors that InstallCore causes on affected computers.

What is the Meaning of InstallCore and Similar PUPs

InstallCore makes unwanted changes to the browser settings. Some of these changes may include the following:

  • InstallCore may change the affected Web browser's default search engine and homepage.
  • InstallCore may add advertisements to websites viewed on the affected Web browser.
  • InstallCore may lower the affected Web browser's security settings and change the affected computer's settings to start up automatically when user starts up Windows.
  • Changes to the affected computer's settings make removing InstallCore from the affected PC difficult.

The InstallCore removal process may be difficult because of various strategies, such as leaving leftover files on the affected PC even after the computer user has uninstalled InstallCore. One problem that has been reported regarding InstallCore is the fact that InstallCore may return if not uninstalled correctly.

Dealing with InstallCore and Similar PUPs

PUPs like InstallCore are used for one purpose: to make money at the expense of PC users. Although InstallCore is promoted as a way of gaining extra browser functions, many of these special offers are questionable or require computer users to fill out surveys or visit suspicious websites.

InstallCore may display numerous advertisements and unwanted content on the affected browser, making it extremely difficult to use and irritating. InstallCore may insert banner advertisements and in-text links on Web pages viewed on the affected browser. This PUP may also cause the affected browser to display pop-up windows and cause numerous performance issues. For example, affected Web browsers may freeze, crash, or slow down significantly, often failing to load Web pages entirely. InstallCore may also affect search engines used on the affected browser, making them display advertisements rather than real, useful search results.

PC security researchers advise removing InstallCore with the help of a reliable, fully updated malware removal tool capable of detecting and removing PUPs. Once InstallCore has been removed, computer users should restore any settings changed by this PUP to their defaults.
