Google Webmaster tools is reporting a large increase in 'not found errors' on my site, and I see approximately 1700 'Not Found Errors over the past 2 months. All of them are for a url that is formatted like:http://mydomain.com/click.php?c%3EdHm7fnGkc3Smdz6kc31%3E'dmjdlgsbve%3E2'lfzxpset%3EQfbs'sbol%3E2'f%3Evt%3Cvt%3C79%3C2%3C2%3C54528243%3Cgmbnjohpspbe%3C2%3C6224'vsm%3Eiuuq%264B%263G%263Gxxx%2Fopdmjdlz%2Fdpn%263G'gffe%3Eopqbz'qsjdf%3E'tbq%3E%3A84%3A9g54e662db639%3A28eeb2cc8bb8e9'zbsht%3Exxx%2Fopdmjdlz%2FdpnGoogle says these are linked from:http://mydomain.com/index.php?Keywords=Pear&search_type=related2&cat2=Lemon+Cake&r=c%3EdHm7fnGkc3Smdz6kc31%3E'f%3Evt%3Cvt%3C79%3C2%3C2%3C27748763%3Ctuzmf2%60dvtupn/dtt%3C3%3Cjoufsdptnpt%60bggjmjbuf%603%60e3s%60efsq%3Cgmbnjohpspbe%3Cgmbnjohpspbe%3C656178%3C6224%3Cdmfbo%3Cmjtujoht%3Czbipp%3C'jqvb%60je%3E:84:9g54e662db639:28eeb2cc8bb8e9'enybsht%3Eg4dc139e6673d:812b:b::d8e34:9fe9&rd=1When I browse to the url Google says these are linked from (both using my browser, and the fetch by Google tool), I don't see any links on the page to click.php. These links are supposedly coming from MY domain / server, but click.php does not even exist on my server. When I look through my server logs, I do not see any of the index.php? urls this says they are accessed from.What am I missing here? Is the link getting encoded in the url or something? How can I fix this? I would REALLY appreciate some help in figuring this out.Update:I had purchased a domain (that was previously parked), and moved my site to it a few months ago. Apparently these links existed on the parked domain, and Google has gone through and crawled all ~1700 of the links twice now. Once a few months ago, and once 2 days ago. Is this something that will affect my ranking in Google? Is there any way to notify Google that all of these links are gone / incorrect? Should I use the 'remove urls' tool in webmaster tools?

These links are supposedly coming from MY domain / server, but click.php does not even exist on my server.This sounds like a server or web application exploit. You should likely run a virus check and a web application security scanner. You should also configure your web server to return a 410 Gone error for any requests containing click.php (or pattern only found in the bogus URLs):410 Gone Indicates that the resource requested is no longer available and will not be available again. This should be used when  a resource has been intentionally removed and the resource should be  purged. Upon receiving a 410 status code, the client should not  request the resource again in the future. Clients such as search  engines should remove the resource from their indices. Most use cases  do not require clients and search engines to purge the resource, and a  404 Not Found may be used instead.
