Microsoft Security Essentials & BitDefender

[ee61re]

WWS - MSE does what Defender does, and more.

Its unobtrusive, free for personal use, and also now free for SMEs up to 10 PCs

If you Install MSE and have bit defender activated , it will be disabled after Installing MSE,Not Bad recommend for my pc basic users !

I'll watch for that but in the meantime, it doesn't really answer the question... are MSE & BitDefender complementary or orthogonal or conflicting?

I switched to Microsoft Security Essentials on the promise of a small footprint AV solution, it lasted for 3 days and I switched back to AVG (Free). There seems to be a long running issue where the msseces process takes up ~50% cpu time (explorer.exe takes up most of the rest) and there is no reliable advice on what the cause/solution is.

I already have BitDefender, which I think is a malware-only scanner? I'm installing MSE now, does this mean I should remove bitdefender or leave it?
