1. On 8 April 2014, Microsoft stops support for Internet Explorer browsers running on Windows XP. This will put your computer and data, such as credit card and online banking details, at greater risk to hackers and malware.

2. Several browser alternatives exist, but we at AVAST use and recommend Chrome, as we find it to be the most-secure option available.
