No to the app killer. Don't waste your time. I don't use an anti virus, but I did for a while. I honestly don't know how effective they are since its a fairly new issue. I did have AVG for a few months and I liked it. It scanned everything that I downloaded. It did slow things down a bit and I think it also drained the battery just a bit, which is why I dumped it. It can't hurt to load one, but I just got tired of the constant scanning. I'll take my chances for now.
