I am accessing Heroes and Villains via this method:
Operating system: Linux Ubuntu
Browser: Firefox
For some reason this method is the subject of multiple attacks by Adware/malware. I have found a solution by a Firefox extension called Total Adblock, but when I'm on the H&V site you can see the counter of Ads blocked go up almost exponentially it seems. I don't know if there's anything that can be done about this but I thought it may be useful info to pass on.
