Help Randomly keeps ringing for some reason...

[Javarr]

Hello fokes, hoping someone can help me out with this. About two days ago, my LG Ally decided it wanted to start ringing anytime I would put it into "standby" I guess the term would be for it (When you hit the hang up button to turn off the screen.). At first I thought it might of just been a glitch, so I tried powering it off and then back on. As soon as it loaded back up, it started ringing again and will not stop till I put it in silent mode. If I take it right back out, it'll be alright for a few mins, then start doing it again. I have tried running at least two anti-viruses over it (AVG and Dr. Web) and nether have found any threats. I even uninstalled all of the apps that I had recently installed on the phone, but to no avail. Any help on this would be great cause having a phone restricted to silent is kinda dumb. >.>;;
