A10: Potentially Unwanted Applications are programs that are not necessarily malicious, but may affect the performance, reliability or behavior of your computer. Such applications usually require consent for installation. Often computers will function differently after Potentially Unwanted Applications have been installed. Typical changes include:
- New windows with advertisements or warning messages which you have not previously seen appear on your computer.
- New processes are installed and run on your computer—often, they are hidden or masked to prevent casual discovery.
- The computer responds slowly or displays error messages when performing normal operations that previously worked correctly. This change is often due to increased use of system resources by the Potentially Unwanted Application.
- Changes in search results
- You may notice your computer making unusual connections in order to transmit your web-browsing habits or other metadata to remote servers, and to download advertisements and search results based on this information.
NOTE: Removing Potentially Unwanted Applications may cause other programs that came with them to behave erratically or no longer work.
