Norton Antivirus Expired

Adding adblock plus or ublock browser extensions works wonders as well.

Any machine that I get that has Norton or McAfee quickly becomes acquainted with either the SYMNRT or MCPR application. (Symantec Norton Removal Tool and McAfee Consumer Products Removal tool.)

Windows Defender and some common sense (don't open suspicious attachments, avoid visiting sketchy websites, etc.) should stop most threats.
