For what it's worth,I've previously used both the Avira Security Suite and Antivir Personal and I was always having problems. With the
Security Suite it was mainly FP's and with Antivir,it was the updating. Back then,my computing knowledge was zilch so maybe I might
have stayed with Avira if I'd have known a little more then and had the Avira forums support had been a little more helpful!
I've gone from Avast to Avira,dabbled with MSE and now back with Avast5 which runs seamlessly with Malwarebytes(Full),Superantispyware
and Vista FW and when I've felt the need to contact Avast forums, good friendly advice has always been available. I'm sure,both have
their pros and cons but as David said in his earlier reply,helpful and friendly support is essential to those of us who are not as
technically "savvy" as some others.
Best Wishes to all,
