Sometimes I visit sites using "incognito" in Chrome so that it won't save any browsing history. These sites give me pop ups, direct me to sites that I didn't intend to go to, and is just overall sketchy and laced with advertisements. Is there any chance these sites could give me malware, adware, viruses or spyware? I'm coming form a PC, and these kind of sites definitely do give all of the above to PCs. Thanks. EDIT: I do not install anything on my MBPr when visiting these sites. Just browse.
