And if that’s not enough… Increase your security by automatically updating other programs on your PC

Hackers count on people to use outdated versions of such applications as browsers or PDF readers, so most virus and malware threats exploit security holes that newer versions fix. As it’s annoying but vital to update all those programs manually, Premier’s automatic Software Updater does it for you – to make sure you’re using the latest versions to close those security holes.

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.
