This is not an A vs B thread, of-course! Hi Guys, For the last year and half, I have been not experimented any antivirus/security suite, and I was more than happy with WSA+MCShield+On-demand Scanners. Now, after installing Windows 10, I am thinking about changing my habit. I tried Windows Defender for a brief while and then switched to F-Secure AV. However, F-Secure is not playing well with my PC, and thus I am thinking about switching to the now-popular choices Baidu or Qihoo (aka 360). Since, I was out-of-touch for much longer period, I haven't followed their developments. Last time I tried these two software myself, they looked similar in appearance to me. So, I have a few questions, 1. Do they have the same engines, or some engines in common? 2. Are they featurewise alike? 3. Which one is relatively more bug-free, light-weight and effectively supported (update delivery etc.)? 4. How good they play along with MBAM Pro? 5. And, how are their Windows 10 compatibility? Thanks in advance guys!
