I recently visited a website and I clicked a link suddenly a new tab appears about a survey. Was that a virus?
You have to disable Pop-Ups. Just click on Customize and control --> Settings
Click on Show advanced settings
Then Privacy --> content settings
Then Pop-ups --> Do not allow
Also go to Customize and control --> Settings --> Extensions, and search for Ad Block, and choose an item from the list.
No it probably was just the website opening a new tab, which although annoying doesn't have to mean you got a virus;)
