I've been using AVG free version for many years. It works great, and I have had zero issues with my earlier Windows XP and now Windows 7.
Lots of great choices out there with most being free.

But do they provide sufficient protection? I don't think so. Last week the email passwords of 16 million Germans were stolen due to a botnet attack.
I can only base it on MY actual real world experience, just like everyone else will do, hopefully.
Many years with AVG free...two different systems...never an issue...not one...I do a lot of downloads/uploads.
As I said, there are plenty to choose from. AVG is one of many.
