I was trying to figure out a difference between extract>run and unzip>install regarding a software I downloaded in a .zip folder, tried to download Winrar but I can't open https sites so I declined to 'jZIP'; unsatisfied, I uninstalled jZIP. I was shocked when I started my browser: it loaded search.jzip.com; new tab still search.jzip.com. I cleared the address bar, input and address, as was loading search.jzip.com suddenly was in the address bar. I disabled all plug-ins that seemed new, re-started but all to no avail! Now my questions: How can I get rid of jZIP? Why can't I access any https site? please help.
