Recently my site got hаcked. They created lots of redirection to 3rd party website from my website. Google had let me know about this issue. So I cleaned up my site and also informed Google for review. Good News is that, Google has white-listed my site. But the problem I am facing now is with those links which they created are now redirecting to 404(not found) page generally as those spammy url doesn't exists into the site anymore.
But today I saw that there are 168 not found error from Webmaster tools> Crawl Errors> Not Found (Google as emailed me about this Increase in "404" pages on ...)
Can anyone please let me know what to do now or how to fix this?
I might not clear with my concern to some people so please ask me for any clarifications.
I've attached a screenshot which shows the spammy urls which they created and currently showing under Webmaster tools
