Go into your Windows Task Scheduler, and you will see those two tasks listed there. If you didn't create those tasks yourself, then chances are that some form of malware created them for you, in which case you should delete them from inside Task Scheduler. After you've deleted them, they will no longer show up in your scans. It's possible that some legitimate software created those tasks, but if that's the case, there will be a description of what each one does, and it should tell you who created it. Most such tasks are for automated downloads of software updates, but in my experience, legitimate software will never install something to the task scheduler. The task scheduler is most often used by malware.
