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:
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.

I used the following script
cd pathname
for y in `ls *`;
do sed "s/ABCD/DCBA/g" $y > temp; mv temp $y;
done
and it worked fine for finding and replacing strings with names etc. in all files of the given path.

Is there a reason why all of these examples of linux find and replace in multiple files use find and grep to pipe into sed or perl. Why not just use sed or perl directly with something like this?

getlastlogx
GETLASTLOGX(3) BSD Library Functions Manual GETLASTLOGX(3)NAME
getlastlogx, getutmp, getutmpx, updlastlogx, updwtmpx, utmpxname -- user accounting database functions
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <utmpx.h>
struct lastlogx *
getlastlogx(const char *fname, uid_t uid, struct lastlogx *ll);
void
getutmp(const struct utmpx *ux, struct utmp *u);
void
getutmpx(const struct utmp *u, struct utmpx *ux);
int
updlastlogx(const char *fname, uid_t uid, struct lastlogx *ll);
int
updwtmpx(const char *file, const struct utmpx *utx);
int
utmpxname(const char *fname);
DESCRIPTION
The getlastlogx() function looks up the entry for the user with user id uid in the lastlogx(5) file given by fname and returns it in ll. If
the provided ll is NULL, the necessary space will be allocated by getlastlogx() and should be free()d by the caller.
The getutmp() function fills out the entries in the struct utmp u with the data provided in the struct utmpx ux. getutmpx() does the oppo-
site, filling out the entries in the struct utmpx ux with the data provided in the struct utmp u, and initializing all the unknown fields to
0. The sole exception is the ut_type field, which will be initialized to USER_PROCESS.
The updlastlogx() function tries to update the information for the user with the user id uid in the lastlogx(5) file given by fname with the
data supplied in ll. A struct lastlogx is defined like this:
struct lastlogx {
struct timeval ll_tv; /* time entry was created */
char ll_line[_UTX_LINESIZE]; /* tty name */
char ll_host[_UTX_HOSTSIZE]; /* host name */
struct sockaddr_storage ll_ss; /* address where entry was made from */
};
All the fields should be filled out by the caller.
The updwtmpx() function updates the wtmpx(5) file file with the utmpx(5) entry utx.
The utmpxname() function sets the default utmpx(5) database file name to fname.
RETURN VALUES
getlastlogx() returns the found entry on success, or NULL if it could not open the database, could not find an entry matching uid in there,
or could not allocate the necessary space (in case ll was NULL).
utmpxname() returns 1 on success, or 0 if the supplied file name was too long or did not end with 'x'.
updlastlogx() and updwtmpx() return 0 on success, or -1 in case the database or file respectively could not be opened or the data not written
into it.
SEE ALSO endutxent(3), loginx(3), utmpx(5)HISTORY
The functions getutmp(), getutmpx(), updwtmpx(), and utmpxname() first appeared in Solaris. getlastlogx and updlastlogx first appeared in
NetBSD 2.0.
