I'm working on troubleshooting a feature that works for most users, but does not work for some. The users that have reported the issue seem to all have the following user agent string:

User agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0; MALC)

So looking at the string it's an IE9, on Windows 7, 32-bit version of Internet Explorer is running on a 64-bit processor, running as IE9 (Trident/5.0 and MSIE 9.0 match).

However, I have no idea what MALC means. Googling it didn't get me any leads. Please help.

The informations above are wrong. MALC doesn´t Mean Multiple Access Line Concentrator. MALC is a OEM identificator for Lenovo Thinkpads or Laptops.
