NIS 2012 Safe Mode scan, is this for real?

Just did a safe mode scan in Win7 with these results:

 

wllogin_32.msi

hpsupportassistant.msi

quickweb32.msi

237c4.msi

b6116.msi

 

These compressed files are all reported as having threats inside, and Norton wants to delete them.

Is this a false positive? or should I let Norton handle them?

 

It also found and resolved ws.trojan.h
