I've used AVG for a long time now without any complaints.
I did have a brief spell with Kaspersky, as my bank was offering it for free, but found it obtrusive & clunky - updates took a long time to load, scans were very slow & just about any online operation triggered a Kaspersky popup. The last straw was when I was buying something online which went to "Verified by Visa", which Kaspersky forced into a new window - when I'd verified the payment I couldn't get back to the merchant's website to check the order details!
The bottom line is that I'd rather pay for AVG than have Kaspersky for nothing! Shop around & it can be very cheap - I bought a 4-user (only need 2) 2-year licence for under £30 from Amazon.
