I've got this really irritating piece of adware - perhaps it's even a full-blown virus - called Trovi on my Macbook Air which I cannot get rid of. It appeared when I was asked to download a Java update a couple of days ago. It now looks like that was just a ruse to get it onto my machine and now every time I open up Chrome, Safari or Firefox it's there, acting a search engine window powered by Bing. I've Googled to try to find out how to clear it. Some people suggested downloading ClamXav or Mackeeper. I've tried both and neither works. Someone else suggested changing the setting in the search engines because Trovi gets your search engine to make it the default. On Chrome, I changed by default search engine back to Googled and then removed every possible search engine from the list in advanced settings. That didn't work, either. Still got Trovi when I click on Chrome even though it tells me that my default search engine is now Google. Makes me think that these poisonous people have recently updated their software to get round these attempts to ged rid of it. I've found a couple of programmes which claim to get rid of it but they are all for PC. Anybody got any ideas? Would it help me to delete the Java update which caused all the problems in the first place and if so, how do I do that?
