I have a problem that Malware Bytes can't seem to find. I've been using the same MacBook Pro (OS X Yosemite 10.10.5) for nearly 10 years, and I have had no more than 2 or 3 problems with malware and things of that nature. I use Chrome as my browser for most things, and Google is my default search engine. Over the last few weeks, when searching in Google, my browser will redirect me to Bing on occasion. So, for example, let's say that I google "how to change a tire on a car." The search results will come up in Google, and I can click on one of the results, lets say How2FixCars.com. Typically, when I do a search, a new tab doesn't open up, but what happens now (occasionally) is that a new tab will open up, taking me to How2FixCars.com; meanwhile, the old tab with the Google results will switch to Bing (with the same search terms). Once in Bing, something even more annoying happens -- if I click on a result, say TireFix.com, it doesn't take me to TireFix.com; instead, it will take me to some semi-related site, selling something like cars, car wax, or whatever. The really odd thing is that it doesn't always happen. I'd estimate that I get redirected to Bing maybe 1 in every 5-to-10 searches -- very strange. It's obviously annoying, but I am concerned that whatever is on my computer might be doing something even more sinister than redirecting my searches. I would really appreciate some help. Thanks so much.
