This question of who is better is very relative.
Both are very good, but you got to see some situations.
You can pay by Kaspersky license, or already have a license? 360TS is free. Second thing: Test both and see which you like best and fits you.
Now in my own experience: Kaspersky undoubtedly. Why:
360TS still has many bugs as the upgrade engine, it is unacceptable for me, installed here had many false positives, detected the video drivers my mother board as a poss trojan, detected updates from windows update even though I have all installed they do not have my language, does not receive updates of bit engines and avira in real time, and not in its entirety.
The weaknesses of Kaspersky for me: Just Startup the program late, it bothers me a bit, and that nothing be paid out more.
Positives of Qihoo to me: great cloud, Mid proactive defense, be free with no light and have a lot of options.
Kaspersky positives for me: A big motor higher than Qihoo antivirus, a better structure and a lojistica in my opinion better and more reliable for years to be on the market, is fully consolidated, proactive defense median, great internet filter and exploits and phising, a good firewall, a lot of additional options far exceeds those of Qihoo and thousands of updates daily. At least not here in my middle weighed notebook.
Is my opinion #
