Is there any advantage to the other spy/malware progs over Spybot SD & Teatimer? I've used this and AVAST for years, so it's what I am most familar with, but if there is another superior product, I'd be willing to change it.
I'd suggest you continue using Avast as well as running an updated MalwareBytes' Anti-Malware scan a few times a month to make sure that things with your computer are clean. If Spybot SD & TeaTimer is a program that works for you then you should keep on using it.
Hope this answered your question.
