msa.exe does not have any version information nor a digital signature. It smells malware to me.

msa.exe is distributed by some faked movie sites. The faked sites are often dubbed "PornTube" or "PornTube v2" and looks like the popular YouTube.com movie site. The "PornTube" sites often claim that you have to install some new codec or the latest Flash player in order to watch the movies. If you installed their software file, you may get infected with msa.exe.

msb.exe is also installed in the same way:

msa.exe is still distributed from many "PornTube" sites. 4 additional files also appeared on my system: a.exe, b.exe, c.exe and msxml71.dll.

Seems like msa.exe does a good job escaping the anti-virus programs. I've ran it through the scanners at virus-total, and at the time of writing this variant of msa.exe is only detected by 3 of the 41 antivirus programs:

My ZoneAlarm 9 internet Security Suite found 'msa.exe' on the basic scan within 2minutes of the scan in the 'start up items'.. I didn’t even know I had it on my computer since the last 8 days!.. ZA gave me a choice and one of them was 'delete on reboot'..Selected this and now I don’t have it anymore! I have not had a virus for 3 years and I don’t know where this could have come from as ZA is the best and 99% of the time it picks up viruses before they can do any damage. The strange thing is that I haven’t had any pop ups or any problems or changes in behaviour from my computer and have had this on my computer since the last 8 days. I hope my personal details haven’t been compromised! :@

Spybot Search & Destroy found the MSA.EXE, In fact it was TEATIMER that caught the process right off and offered to delete the asosiated files. In my case though, MSA.EXE was popping up IE popup ad/search windows every 15 minutes :P

I don't know if Spybot destroyed and fixed the problem, Am looking for an antimalware SPECIFICALLY catered to msa.exe to doublecheck but so far so good. :P
