I have been using Avira Free with a Windows 7 laptop for several years and it's been ok, but there are quite a few annoying pop ups and I suspect it's dragging the performance (boot times) a bit.
I recently switched from Avira Free to Windows Defender on a Windows 8 laptop and I have been pleased with the results so far. Faster start ups and no pop ups.
Now I am thinking of switching the Windows 7 laptop, but I understand that Windows Defender is not an antivirus option (only anti spy for Windows 7)? So I would need Microsoft Security Essentials (MSE) instead.
Has anyone switched to MSE for Windows 7 and willing to share their experience? Thanks!!
