  • I have used Avast and AVG for a long time now and had no problems with it! I don’t understand why people wish to pay for Antivirus software!

    • Yeah, we need not to pay for Antivirus software. Many times, we can find many great promotions that give out free licenses key of our favourite Anti-virus software like Antivir Premium, McAfee, Kaspersky. When the license expires, I will switch back to free Antivirus for a while until I find another free license offer.

  • I used to be a big lover of free anti-virus application, until one good day.. Viruses started and eating all my files.. I had no choice other than formating my hard disk. I wish i can share what my feeling was, after that I started my relation with Premium nod 32 and malwarebyte..and See my smile 🙂

    • It’s bad to hear that. Nowadays, I seldom use free antivirus because there are many promotions that offers free license keys for several commercial antivirus products. Most of the time, I use those free license keys. 🙂 I change from one product to another when the license expired.

  • I had a lot of problems with Microsoft Security Essentials, as you can read in my blog post.
