Well, my hard drive broke and I installed a new one.
I was once the No. 1 Qihoo fanboy, but now after what happened (and because it was not all that happened and would not surprise me to spend more ) plus hard drive configuration change and this is where your advice is welcome, this is not a closed configuration, I doubt between Panda and Avira, put or not an external firewall (torrent downloaded and I test freeware software) ...
Security: Panda free Crystal Security RC2.
Demand scan: Malwarebytes free and Xvirus
Cleaners: Kerish Doctor, Wise Care and Galrys
Browsers: Yandex (very comfortable for those who visited websites in another language) and Cyberfox
Extensions: LastPass, HTTPS Everywhere, Ghostery, ublock Origin and Adguard (I hesitate between the last two and together do not bother)
Backup: Backup Ocster 7
Mail: Thunderbird
Privacy: Privazer
P2P: Deluge and Emule (the latter is easier to find less commercial music)
Media Player: VLC (Pot Player is another good option, but its translation into Spanish has to improve)
Uninstaller: Soft Organizer and Max Unninstaller
Office: LibreOffice (there are other good alternatives, but some are not in Spanish)
Other: Notepad ++, Clover, System Explorer, Bandizip, Ashampoo Snap 7 FarstStone Viewer, Everything, QTranslate, PowerISO, BurnAware free and Left4Dead, the essential soft.
All your advice and / or comments are welcome.
Thanks and have a nice day!
