Here is a comparison of the two so you can decide which is better for you.  Both of these AV’s have their positives and negatives. Combine any of these Anti-virus apps with Chrome browser which also detects some viruses and Malwarebytes.  You will then have a very strong fortress.  Here is the good and bad of these AV apps.  Both of these have low resource usage in my opinion, especially MSE.

Avast avast vs mse

The Good

  • Avast has shields that work at real time.
  • It’s Free.
  • I.T. workers recommend it as one of the best.
  • Is better for safe online surfing practices.
  • Avast has been able to block every single bad site that tries to insert something on my PC.
  • It rarely blocks anything that’s legitimate.

The Bad

  • Avast can at times interfere with other programs.
  • Prompts you to register the Free version.  (Starts you with 31 days free until you register free version).
  • Some people reported that it causes BSOD (Blue Screen of Death)
  • It has frequent popup alerts prompting you to update apps installed in your PC, and also prompting you to integrate into Chrome.

 

MSE (Microsoft Security Essentials) avast vs mse antivirus

The Good

Is lightweight and light on resources.  It’s hard to notice that it’s even installed at all. It’s Free  

The Bad

  • I have noticed at one point, that when Malwarebytes found a malware in my PC through a manual scan, MSE just happened to also popout the moment Malwarebytes found that Malware.  This doesn’t make MSE look professional.
  • Poor virus definitions.
  • All MSE does is look for a definitive virus signature, rather than something that may be a virus.
  • Microsoft Security Essentials loses AV-TEST certification, see below article. That low detection rate has cost it the AV-TEST Institute’s seal of approval’. http://www.theregister.co.uk/2012/11/30/microsoft_security_essentials_loses_av_test_certification/
