Yes, as long as you have configured your settings right. Click Monitor and if you see any action, then other hosts are uploading from you. Also I would suggest taking some time to read the Stickies on this forum because it is loaded with very valuable info to assure a good experiance. There are tons of corrupt files out there in addition to the worms and viruses. So make sure your AV is updated and scan all files before you open them if possible.
