Anyone know how to control their home computer from work

Just wondering, I don’t want to do much, just maybe get my home PC to start new torrents or something like that. It’s on all day anyways would be nice to peak in on it once in awhile. I think we have an average firewall at work. Any programs or links about this, I don’t want to be hacking into anything that can get me into trouble though…

Can rip through whatever.
