The big ones Im running into right now are: 1) The Isis Virus. Your system will get a screen coming from the Department of Homeland Security saying that your system has been flagged for <insert technobabble here> offense and is assisting ISIS. You MUST call <insert bullshit number here> and report this screen showing up or your computer will be confiscated and you'll be charged with <insert bullshit charge by FBI/CIA etc>. 2) You'll be emailed, IMd, or contacted via phone by someone claiming to be either a partner of Microsoft's OR Microsoft themselves saying that your computer has been compromised/having issues and then will request access to your computer via remote. Once they obtain access they infect your computer and the virus above pops up, or another screen that "locks" you out and says you must pay an $800 fee (more or less) to have it fixed. Most of us here are pretty intelligent and tech savvy, but our elderly family/younger family members may NOT be. Have them contact their ISP if this stuff pops up and let them know, change all the passwords for their banking etc, and if its a phone call, report the number that contacts you to your local PD's fraud squad.
