1.) I setup my browser (IE/CHROME) to connect via PROXY when using only HTTP @ 127.0.0.1:8118 (PRIVOXY) CONFIG Screenshot: http://i41.tinypic.com/xelpoj.jpg 2.) Then I installed PrevX SafeOnline Facebook edition. PrevX automatically activated its Proxy Support. The settings looked like this: http://i40.tinypic.com/eg61ol.png After clicking Save changes. It will show up the scanning interface but it won't start. After a second or two it will return to its Proxy Settings interface. The scanning continued after I changed the settings like this. http://i40.tinypic.com/mug30j.jpg There might be a bug when PrevX detected browsers using proxy on HTTP(only). Also analyzation (http://i44.tinypic.com/2uprdwo.jpg) shows up but not also working when using http=127.0.0.1.......... Therefore cannot proceed full installation.
