      Avast Free Antivirus vs Windows Security opinions
      This alternative is disputed. Avast Free Antivirus is still a legitimate alternative to Windows Security, but it might have issues that some users think are important.
      Don't trust these big-name security suites, they're crap and full of bloatware. Same goes for AVG, Avira, Comodo. When they get on your system they just take over and nag you to buy whatever...
