I dl’d the malware and did a quick analysis. Virustotal is a little less than helpful:

http://www.virustotal.com/a…

but I did some rudimentary strings analysis. Its packed with an unmodified UPX so easy to unpack. The following URLs are in it:

DON’T GO TO THESE!
hxxp://mycashloads.com/newuser.php?saff=
hxxp://windows-privacy-protection.com/?aid=

It also looks to be written in VB6 as I found this in it:

C:\Program Files\Microsoft Visual Studio\VB98\VB6.OLB

as well as some VB-related function calls.

There were also a bunch of these types of messages:

Your computer is infected with spyware!
Windows has detected spyware infection on your PC.#CR##CR#It is recommended to u
pdate your antispyware protection to prevent data loss. Click here to download a
nd install the most up-to-date antispyware for you.#CR##CR#Click here for more i

Warning:

ove spyware!#CR##CR#Click here for more information…&

and so on.

If I had to guess, this is a trojan downloader which would trick you into downloading rogue anti-spyware software by putting those "You’ve been infected" messages on your system. IMO (and from the limited stuff I’ve looked at on it) its not specifically bot-related…however, the stuff it downloads might be.
