I am helping a friend with her macbook pro. Now I know you MAC folks will take offense to my use of saying it has a virus but it does have issues with a movie she downloaded and it sounds like she also installed an app that she used to download that movie. I can't seem to get a clear explanation of exactly what happened. She did say that she got one of those fake calls from "apple support" saying they are calling to help her--but she hung up on them and asked me for advice. Told her to just turn it off and bring it to me. Now trying to use chrome and doing any kind of search takes you to websites we don't want to go--similar to been hijacked in Windows. And if I try to go to sophos to download its app for virus the download page in chrome continuously refreshes and is impossible to click on what I downloaded (I used safari to download it and then installed it). It is running now and says it has found some issues (not sure what they are yet--has been running for 3 hours already). At this point I think the best thing to do is to reinstall osx but wanted to make sure you mac experts agree with me. Most apps take a very long time to start and intunes won't play any music or videos. My plan is to do a backup and then boot into the recovery partition and reinstall--is this the best thing to do considering the above? If you agree with me how do I make sure that none of the data that gets backed up is infected? Anything else I need to think about/prepare for? Thanks.
