This should be developed instead of TS versionGo with 360 Internet security (NOT TOTALSecurity) and you will not regret.
Reasons to choose 360 Internet Security:
2) TOP detection rate even better than some paid AVs
3) Very light (On windows 7 WITH Bitdefender engine enabled it consumes approximately 30 MB).Also windows starts very fast.
4) Stable program (NO crashes , no bugs,no system instability)
5) Very good support team
6) Very good Proactive Defense (system protection, registry protection, download protection, file protection, driver protection, network protection etc)
7) It blocks keyloggers and also protect your camera (if you use one) from being used by other persons
8) Updating 2-3 times per day instead of other free AVs that update 1 time per day
9) Color themes and settings to play with
10) SANDBOX that can isolate suspicious programs especially when you are not connected on the internet.
11) Instant cloud analysis of suspicious items
12) Very fast scan times
The choice is yours
