I have been looking for Free antivirus which don’t affect the performance of my machines.
The top options as reviewed by techradar and PCMAG are the usual, AVG , Panda and AVAST but this time around I have possibly found the best option out there – Bit Defender.
Bit Defender scores well by:
  • Using a clean light interface
  • Does not consume resources
  • Has proven to have a good real-time shield
  • Is effective in catching malware, both from test scores and my personal experience.
  • Is free
  • Found a Trojan on my OneDrive which Microsoft had been missing for weeks..!

Like all things free there are drawbacks:

  • Lack of configurability
  • A nonexistent(?) quarantine management function

By logging in with an account of your choosing you get unlimited free protection – otherwise its limited to 30 days and of course the paid version will offer much more in terms of all round protection.

For advanced user who are well aware of where not to stray off too and with a decent awareness of the security threats on the internet this definitely a tool that I recommend exploring.
