Yes it is certainly weird behaviour, but currently not malicious as far as I can tell, but that rather depends on what the pop_int.js does, but avast doesn’t alert on it and zero hits at virustotal either.

So it rather depends on what might be at the other end of the iframe, which appears to be some sort of sponsoring, given the check_bot=‘domainsponsor’ bit at the end, see image.

Now I use firefox and the NoScript (NS) and RequestPolicy (RP)add-ons, NS would primarily stop scripts being run on the gla55pak.com site and RP would stop cross site scripting (on searchportal.information.com), it is this bit which would block the redirect to whatever the sponsor domain might be (check_bot=‘domainsponsor’).
