What to do with virus's??

Hello, we are having a bit of issues with some virus's on some pcs. 
We have setup our policy as recomended by our sophos trainer so on detection of a virus sophos AV just blocks access and does not automatically delete the virus. (to allow false positives etc),

We now have around 50 pcs in the console with random virus's like below...

20/09/2010 05:03:55  Virus/spyware  Mal/Iframe-F                  C:\Documents and Settings\user\Local Settings\Temporary Internet Files\Content.IE5\WIFM3FC2\novelty[1].htm

and 

22/09/2010 11:00:37  Virus/spyware  Not cleanable  W32/VB-CVP                    C:\fun.xls.exe      

We need to delete these files from their machines now we have checked that they are not random false positives. Is there anyway to get sophos to delete them from the console? The only option I get is clean and acknowledge, clean fails and I dont just want to acknowledge it! . 

Hope that makes sense!
