I had a job yesterday, basically a scam job as described above.
I was driving to the customer when he phoned me up, panicking.
Basically, there was Indian music blasting at top belt out of his speakers, plus "war" messages popping up on his screen.
When I got there, I found aa_v3.exe running, plus some files called djpunjab.
This was a pretty straightforward cleanup, which I followed by a series of scans, plus an sfc for good measure.
What amused me was this. The Indian guy called back whilst I was there. My customer took the call and said the problem was fixed and hung up.
I then started counting down from 10 to 1 out loud.
My customer laughed at me, saying "he's not going to call back is he"!
When I got down to "2". The phone went again.

My customer was called another 4 times within the next 3 minutes.
These scumbags are nothing, if not persistent.
