It's dangerously easy to assume nothing bad will ever happen to you. Viruses and computer hacks happen to our students. Again, please take this seriously and we can avoid most of it.
When major viruses and hacks break out, companies release updates to operating systems to correct vulnerabilities. To stay safe, you have to stay updated. Check around on your devices.
Make sure you've got a copy of MalwareBytes installed. It's recommended that you upgrade your account so it runs active monitoring but it's not required. Running manual scans is sufficient so long as you remember to occasionally do so.
With your operating system updated and Malwarebytes running, you're now ready for our last step.
