Update :
Uninstalled BatteryBar, caused explorer.exe to crash
Uninstalled Adguard, had perhaps a filtering problem where the speed of a download would drop to 0kbps and never increase (but good software overall)
Uninstalled Defraggler
Uninstalled Freedome
Installed HerdProtect
Uninstalled Emsisoft IS 10 (extended referral trial). Extremely good overall while I had it, especially in v10.
Bought ESET Smart Security 8 (1 year, 1 pc). Had to quickly configure it twice before that creepy robot face would be permanently carved in my mind. Used it for less than a week, only downside for my experience is the awkwardness of using the advanced setup (please UAC...).
