I'm not sure your plan is the best but here is a suggestion, make a backup first even though there is garbage in there.:
If it is limited to php files (for example), then limit searching with find as step one, then use grep to see if the file is infected, and sed to remove bad strings - sed has to write to a tmp file which at the end of sed processing gets copied back and then re-set permissions/ownership.
psuedocode:
Code:
find /path/to/start  -type f -name '*php' |
while read fname 
do
   grep -q 'malware code pattern' $fname
   if [ $? -eq 0 ]; then
      sed 's/malware pattern//g' $fname  >/tmp/file
      mv /tmp/file $fname
      chown [required ownership] $fname
      chmod [required permissions] $fname 
   fi
done

This has the potential of breaking some code. It also depends on how well you did checking for malware, it could simply reinfect your system if you missed something.
Be sure to get a good backup once the system is running correctly.

clm residue(1)							  USER COMMANDS 						    clm residue(1)

  NAME
      clm residue - extend clustering of subgraph to clustering of graph.

      clmresidue  is  not  in  actual fact a program. This manual page documents the behaviour and options of the clm program when invoked in mode
      residue. The options -h, --apropos, --version, -set, --nop are accessible in all clm modes. They are described in the clm manual page.

  SYNOPSIS
      clm residue -icl fname (input clustering) -imx fname (input graph) [-rpm fname (residue projection matrix)]  [-o	fname  (output	clustering
      file)]

  DESCRIPTION
      The cluster file presumably contains a clustering of a subgraph of the graph G contained by the matrix file, implying that the row domain of
      that clustering is a subset of the node domain of the graph. clm residue will compute  a	simple	upwards  projection  of  that  clustering,
      resulting in a clustering of G.

  OPTIONS
      -imx fname (input graph)

      -icl fname (input clustering)

      -rpm fname (residue projection matrix)
	The name for the file in which the residue projection matrix is stored.  It contains for each node and for each cluster in the input clus-
	tering the combined weight of the (edges to the) neighbours of that node in that cluster.  The default output file name is out.rpm.

      -o fname (output clustering file)
	The name for the file in which the majority vote projection clustering is stored. Aka the majority vote projection clustering storage file
	name.

	This  embodies	a very crude approach to distributing the missing nodes in the input clustering onto that same cluster. For each node, the
	cluster is taken for which the residue projection is the largest (see above). The residue (i.e. the set of  missing  nodes)  is  initially
	viewed	as  a  cluster;  the set of nodes for which the projection is largest for the residue itself will form a new cluster, if it is not
	empty.

	By default output is sent to STDOUT.
