What is IB Updater Service?
IB Updater Service (ExtensionUpdaterService.exe) automatically keeps software created by Perion Network Ltd. up to date. Incredibar, Sweetpacks, SmileBox, these are only a few applications that use IB Updater Service. It's not essential for Windows and may cause problems. It runs in the background and periodically checks for updates (connects to Perion servers) it may slow things down for a while or even use up to 100% of CPU. However, very often, these applications come bundled with adware (Adware.InstallBrain), not to mention that some Perion products are classified as adware or PUP as well, IB Updater keeps various adware applications updated as well. "IB Updater Service" may also show up when users try to uninstall Perion related software (see image below). As you can see there's a a captcha saying that you need to verify that you're human. IB Updater Servic explains that they want to make sure that you are a person and not an automated system. This is a very unusual practice. I recommend you to remove IB Updater Service from your computer.
