  1. I don’t think AVG should have made the list at all. It’s constant nagging pop-ups pressuring you to upgrade your protection to the paid version makes using the computer it’s installed on a truly horrible experience. It used to be good, running silently in the background, but these days…no way.

    • I agree Erica, and Avast has also gone downhill imho (I got infected while using these two last year), while Bitdefender Free takes up too much space (more than 2 Gb on your system partition and can’t be installed elsewhere). Have switched to Avira on all my computers and pretty happy so far.

  2. Appreciating the time and effort you put into your blog and detailed information you present. It’s good to come across a blog every once in a while that isn’t the same out of date rehashed material. Wonderful read! I’ve saved your site and I’m adding your RSS feeds to my Google account.|

  3. No matter if some one searches for his required thing, so he/she wishes to be available that in detail, therefore that thing is maintained over here.|
