"No Actions (full computer scan required)"

Hello all

I have been using Sophos for a while and have no noticed in Quarentine that i have 4 files that Sophos says are Virus/spyware, but i can't do anything with the files. Sophos says "No Actions (full computer scan required" but after doing multiple full scans (Im doing a full scan by scanning the whole computer, i assume thats right) the files are still there.

Any ideas?

Cheers

Sam
