A script file being 3kB zipped? Posted alongside other stuff which is 8.9kB zipped?

viruses? or just other crap?

Should the question and posted files be leigitimate, then you should definitely start by reducing the size of posted code to whatever is relevant. By the time you've done so, you have most likely found the error yourself. If not, someone else will by direct inspection most of the time. So, reduce the code until only whatever is relevant to your specific problem is left. Then post that code directly on the board.

about 8.9kb this is the database
i needn't to upload all project to make it specified but the size for full project is 860 kb and this is not allow to upload so i'll upload only pages i have problem with it .... thank you for your answer:
the problem is in this ajax code:

<script language="javascript" type="text/javascript">

function getXMLHTTP() { //fuction to return the xml http object
		var xmlhttp=false;	
		try{
			xmlhttp=new XMLHttpRequest();
		}
		catch(e)	{		
			try{			
				xmlhttp= new ActiveXObject("Microsoft.XMLHTTP");
			}
			catch(e){
				try{
				xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
				}
				catch(e1){
					xmlhttp=false;
				}
			}
		}

	return xmlhttp;
}

function getMake(id) {		

	var strURL="findmake.php?id="+id;
	var req = getXMLHTTP();

	if (req) {

		req.onreadymakechange = function() {
			if (req.readyMake == 4) {
				// only if "OK"
				if (req.status == 200) {						
					document.getElementById('makediv').innerHTML=req.responseText;						
				} else {
					alert("There was a problem while using XMLHTTP:\n" + req.statusText);
				}
			}				
		}			
		req.open("GET", strURL, true);
		req.send(null);
	}		
}
function getMake(id) {		
	var strURL="findlast.php?id="+id;
	var req = getXMLHTTP();

	if (req) {

		req.onreadymakechange = function() {
			if (req.readyState == 4) {
				// only if "OK"
				if (req.status == 200) {						
					document.getElementById('lastdiv').innerHTML=req.responseText;						
				} else {
					alert("There was a problem while using XMLHTTP:\n" + req.statusText);
				}
			}				
		}			
		req.open("GET", strURL, true);
		req.send(null);
	}
