Not true. If you look at AV comparatives, MSE is slipping. For free better go with avast and a few combos. Kaspersky I trust. Anyway, here is my setup.

avast Free v6
Comodo firewall 5.5 (Put it on training mode and launch all the programs that need internet connection)
Sandboxie free (One of the first thing I install when format)
Malwarebytes
Eset Online Scanner
Panda USB Vaccine Portable
Winpatrol free
Neo's Safekeys (protection against keylogger)
Lastpass
Google DNS

Browser :
-Firefox with WOT, ad blocker plus
-Google Chrome with WOT, ad blocker
-Updated Java and flash

Thinking
G Data Cloud Security/Bitdefender Traffic Light

The above are personally tested by me to find it running light and fast. I will never install something that slows my computer down.
