An acquaintance asked me for help: “My Mac got infected with a virus and search-quick.com got set as the default page, please help!”

This is a case similar to the consultation posted on Yahoo! Answers below.

• The Mac at home seems to have been hit by a virus. As soon as I click Safari... - Yahoo! Answers

First, I had them try the following two things.

• Disable Safari extensions
• How to uninstall Safari extensions | Forest of Random Writings

Furthermore, I had them use an app called AdwareMedic, and they seem to have been able to solve the problem.

• Remove adware installed on Mac without your knowledge with "AdwareMedic" - iPod LOVE

This acquaintance seems to have been caught by a fake site that looked like an Adobe Flash Player update.

We should be careful of suspicious apps and advertisements.

That’s all from the Gemba.
