Hi malware fighters,
In recent weeks various worms appeared that spread massively through Instant Messengers. In two cases it concerns MSN worms with a link to a Trojan downloader. This downloader downloads various adware & adware-related Trojans. The ,alware outbreak has reached an epidemic level, according to av vendor Kaspersky Lab.
Remarkable about it is that these worms spread themselves via .pif files. These kind of extensions are being blocked by the Microsoft filter. But this filter is capital dependant and only blocks .pif files and URL's in small print. ".PIF",
".Pif en ".pIf" are just ignored. Microsoft has been informed of this flaw, but the software-gigant has not reacted whether they will adjust this filter.
