Recently, some users have contacted us regarding suspicious emails they have received. These emails appear to be a notification of an account change and ask you to click on a link to update your settings. These messages are NOT genuine. As LetsHost do not provide MS outlook online these emails can be ignored. However, clicking the links contained in these messages may you to a webpage that will install malware or virus software onto your computer.

Messages such as these are phishing emails sent out at random by a large global network of infected computers and servers called a botnet. The people who control these botnets send out huge volumes of spam and phishing emails in the hope that enough people will respond to make their efforts worthwhile.
Phishing emails will try to trick you into believing that they are from a trustworthy source and can be very convincing. Please be extremely suspicious of any unsolicited email you receive that asks you for sensitive information (such as your username and password) or asks you to download something onto your computer.
