I have a file where I keep all those favorite programs I install from time to time, so don't always trip over the ones that have the malware as much. I did load a newer (supposedly newer) version of Elite Screen Capture direct from the grizzly ape site for firefox extension and it was infected with malware. I uninstalled it, found the older version, changed the install.rdf file in the xpi file to allow installing on later firefox versions and been using it with no problems both in windows and linux versions of firefox. I do contribute to the software I've used the most, like toniarts EasyCleaner, the LViewpro, of course Linux Mint, Wikipedia, but only if I find a continous use for a software or site.
Unless there's some payback for those doing the software, then we'll end up paying more when most of them leave it to big companies to do, and sell.
