Reinfected with aatiircf.exe (Trojan Horse Inject)

Hey guys,

Recently I suffered a met police scarewarevirus. But that has been removed and it's all cool.

I've been running a scan daily and I keep getting reinfected with,
aatiircf.exe - it changes everytime, the ending letter has been 'd' before, not 'f'.
Is this something to be worried about?

What about "rfrdkteo.exe" I can't seem to find a web link for it but it says i've been infected by that thing.

Any help would be appreciated.
