And Avastfan1 this is to be avoided:
Avoid gaming sites, pirated software, cracking tools, key-gens, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology. So I would go for Firefox with NoScript installed and active and the AdBlockPlus extension to block the ads and banners you do not want to show,
Be safe and secure online,
