Malware/virus concern on macbook air
I have an older MacBook Air (bought in 2014). For weeks now, every time I open safari - regardless of what website I try to use, it keeps directing itself back to a “search baron” website, rather than google which is my preferred search engine. And if I try to put in a specific URL the page says gives me a warning about it being fraudulent and stealing private info, etc. I already looked into changing my settings through xfinity, because I had read on another forum that that could’ve been causing the problem. However, even trying my laptop at work and on other connections, it seems like my safari and computer has a mind of its own, as in its taking over and I can’t even complete a task anymore.
I’m assuming this means my laptop most likely has some sort of virus or malware issue - but I am stuck trying to figure out which app is actually going to be effective, because it seems like there are lots of options that won’t be beneficial as far as resolving the issue. Does apple have their own app for antivirus or malware on macs? Other than having the the newest software update.
Please Help!!!
MacBook Air 13″, OS X 10.11
