So am I :) Do you have a virus program (like Norton or McAfee?) If so, run a scan of the executible. The freestuff offerings are not hosted on Rendorosity as I understand it, so Rendo would not be in a position to warranty it. It would be pretty stupid for someone to post a free offering here with a virus in it :) You could also check this persons store or previous free stuff. If they have a store here or have offered other free stuff, then they are probably a good risk :) Ultimately the decision is yours as well as the risks associated with it. I don't run executables from anyone other than DAZ or RDNA. BTW: I also scan all zip files before opening them.
