Problem with my TP2 dialing international calls

[Bulldawg4369]

So starting about three months ago, my phone bill from Sprint showed a $300 balance. When I called to question it they told me that I was calling Dominican Republic for 2 1/2 hrs. I told them it wasn't me and they opened a fraud case. Well the next month on the same date and time another 2 1/2 hr call was made to DR. This continued on and on for three months. Sprint fraud was telling me that there was no fraud and they would not help me. I couldn't figure it out. Then someone in customer care said that there was a known issue with the HTC phones and malware. This could be making the phone calls from my phone and Sprint wouldn't be able to determine it. Then I spoke with one of my friends and he told me about blue hacking and blue snarfing and that with my bluetooth on anyone could use my phone for whatever they like. I want to know if any one here is aware of any of these and what could be done to stop this.

There are a few apps/games out there that have had malware reports. Here is an app that scans for viruses/malware

+1 on what Kliptik said. i use outlook on my tp2. it runs in the background and not a memory hog.
