You download a free app…
Install it fast…
And suddenly, you’ve got a new browser, a “PC cleaner,” and 3 toolbars you didn’t ask for.
That’s software bundling — and it’s sneaky.
Here’s what it is and how to keep your system clean.
1. What is software bundling?
Bundling is when a program installs additional software alongside the app you intended to download.
Some are optional (but pre-checked), while others install silently unless you stop them.
Examples:
-
Adware
-
Fake antivirus tools
-
Browser hijackers
-
Trialware or useless system boosters
2. Why do developers bundle?
-
Extra income via partnerships
-
Distribution deals with third parties
-
Some “free” software exists only to bundle other apps
Not all bundling is malicious — but most is unwanted.
3. How to avoid bundled software
-
Choose “Custom” or “Advanced” install — not “Express”
-
Read each screen during installation
-
Uncheck everything that’s not the core software
-
Avoid download managers or “Install Assistants”
Legit software never forces hidden installs.
4. Use trusted download sites
Stick with:
-
Ninite.com– Clean installs only -
Official developer websites
-
Reputable open-source repositories (GitHub, SourceForge – cautiously)
Avoid:
-
Softonic
-
CNET Downloads
-
Random mirror links on forums
5. If you accidentally installed bundled apps…
-
Go to Programs & Features → Uninstall suspicious entries
-
Use Malwarebytes or AdwCleaner to clean leftovers
-
Reset your browser settings if homepage/search was changed
Key points to remember
-
Bundling = hidden installs during legitimate app setups
-
Always read every screen before clicking “Next”
-
Choose custom installation and uncheck extras
-
Avoid sketchy download portals
-
Clean installs = faster, safer PC
