Not sure if this is the best place to report this, but I installed Dexpot.exe last week and AVG reported a virus backdoor.hupigon5.cbqn and I quarantined it. I subsequently found a post on the AVG forum regarding a similar issue with iTunes. It's apparently an issue with AVG thinking something is this virus. I haven't found a workaround, but am going to un-quarantine dexpot and see what happens.
