Top 5 based on protection, user friendly, bugs, false positives and system resources.
1. Eset Security Suite
2. Avast Security Suite
3. AVG Internet Security Suite
4. Avira Security Suite
5. G Data Internet Security Suite
Reason why some others didn't make my list:
-Kaspersky, heavy system resources.
-Emsisoft IS, high false positives and not user friendly.
-Norton IS, high false positives because of community watch and hard to allow exclusions (user friendly).
-BitDefender, complete bloatware, heavy on system resources and bugs.
-Comodo IS, not user friendly, blocks many safe processes without notifications, high false positives and bugs.
-VIPRE, has many bugs each time I have tried it, especially the update bug where updates fail constantly and the firewall continues to block connections no matter what you do.
-PC Tools IS- complete crap, too many problems to list them all.
-F-Secure, extremely large takes up too much disk space and continues to grow with each update.
-McAfee IS, do I really need to start? I believe everyone already knows.
Never tried the following, because I don't have any experience with them, therefore I could say anything good or bad about them:
Of coarse I have read reviews and then never appealed to me.
-TrendMicro IS
-Norman IS
-Dr. Web IS
-Panda IS
-Rising IS
-FortiClient Suite
Thanks.
