PUABundler:Win32/ICBundler is a potentially unwanted application or bundler detection. It is not always a destructive Trojan, but it can install extra software, change browser settings, show ads, or make cleanup harder than a normal uninstall.
What is PUABundler:Win32/ICBundler?
ICBundler is a bundler-style detection. It usually means the installer may include additional offers, advertising components, browser changes, or unwanted helper programs.
Why Defender or another antivirus flags it
Antivirus products flag bundlers when the installation flow makes it too easy to accept unwanted extras or when the installer comes from a questionable download portal.
- Bundled offers are preselected or poorly disclosed.
- The installer changes search, homepage, new tab, or notifications.
- Extra browser extensions or updater tasks appear after installation.
- The downloaded installer came from a mirror, ad, or software portal instead of the original vendor.
How to remove it
- Let the antivirus quarantine the detected installer or component.
- Delete the original download that triggered the alert.
- Uninstall recently added apps, download managers, coupon tools, or browser helpers.
- Remove unknown browser extensions and notification permissions.
- Reset search engine, homepage, and startup page.
- Check Startup apps and Task Scheduler for unwanted updater entries.
- Run a full scan and restart the PC.
