Michele accidentally clicked on an ad and now she keeps getting pop ups to download "Windows updater." Leo says that's malware and to avoid it. Leo also thinks that Michele hasn't gotten a virus just yet. But since she clicked on the ad, there may be a cookie there that keeps bringing it up. Leo advises running MalwareBytes, but she should only download it from http://www.malwarebytes.org/. There are bad versions out there that are designed to confuse people. Always download software from the original designer.
Microsoft also has software called AutoRuns, which will tell her what is starting up when she boots up her computer.
