Recently attacked by something that has no information on it

Hi all,

 

I recently underwent some sort of attack that Norton blocked and was looking on the forums to check for any info on the file which attacked me. I figured this was a good idea since some files just pop back up again (or, there is some underlying file which downloaded this that may still be on my computer). However, there was nothing on the forums that I could find. So, I figured I would ask you if you've ever heard of any of these files:

 

mshta.exe  <-- The main one, which is the origin of all the others (according to Norton Antivirus 2010)

mnaxocrswe.tmp

xnsoewcram.tmp

xwcnermsoa.tmp

nemowcsaxr.tmp

nxrowcmase.tmp
