This website has lots of malwares and they are blaming it on the host. I don’t think that the host has problems here. I think that this website has a lot of copied codes from various sources online and that is what is infecting the mail server. We just had the website infected with malicious code exactly one month ago, 21st January.
And on the same day this month, 21st February, we have the same problem. Something is seriously wrong. Stanrdard group web guys have promised me that they are launching a redesigned version of the website very soon. With these kinds of problems, we can only wish them well.
