ignore the pop ups, your computers protection software itself will tell you if there is anything malicious on there and remove it for you :] they're just a bunch of ads, if you have google chrome you can get the adblock thing for free (no youtube adverts wuhaay!) so then you wont get the stupid and sometimes disgusting adverts pop up ^,^
I was getting them too. I just shut down Mangago and read my Archive on Our Own site the rest of the night.
If you have chrome or firefox, download the extension Ad Blocker Plus. That will take care of those stupid ads. Also, go into your control panel, and remove the ad software (there are usually 3 different kinds), because it usually downloads onto your computer.
is it just me or does mangago have a virus or something cuz while reading i kept getting pop ups about this site having malicious software that could infect my computer. i love this site but should i b concerned???
