We are using Opencats for one of our domains since long. We have more than 10 users.

Only one user is facing a strange issue. When he randomly clicks on the page, it opens the strange links. Other users are not facing such issue.

Any idea on what can be the issue?

Lock them down to a standard user and prevent them from installing software themselves
