Is my site hacked? Does it have virus?

Hi
Please can you share a link to the site in question. We can then take a look to see what the issue might be.

on google webmaster tool 404 list you can see where they are linked from. if they are out site of your site then you dont have much to do. however, if i were you i would not redirect pages that at any point belong to my site. you should just ask google to remove these pages from google cache. as some spam link building site does link to sites with wrong/generated keywords and google pick them up.

Hi guys!
The site: matoteam.sk

Those spam links are linked from inside. (all redirected now)
Removing pages through Google Remove tool – haven’t thought about this. But I would have to do that on Bing also, bingbot finds some of them too. 301 was less work and faster in this sense. But it seems I’ll have to do it anyway, because those spam links did generated some traffic. And I don’t want this site to be associated with spam sites in any way.
I still would prefer to find the source, and stop spam links from being created again and again.
Thanks for your advices.

Thank you King,
I did this scan before, but still, thank you for reminding me. Glad my site came through verified clean.
I won’t mark this topic as resolved yet.
I’m still facing that “mysterious” cause for google & bing bots finding spam links buried somewhere inside linking to nonexistent pages on my site.
It might be one of my plugins. I’ll try to uninstall one, but I’ll be able to see any changes only after week or two. They are generated irregularly, but in last 4 months I had close to 100 404s.
If I’ll find the solution I’ll update this thread.
I’m still eager to find help here if possible.

Did you ever figure this our? I see this is an older post, but I am having same issue…

try to install Wordfence or BulletProof Security plugins. They will scan your files (themes and plugins) and report any found issues.

Hey,
I think it is fixed now. I hope my understanding of Google explanation is correct. In my research I found that Google bot makes such 404s quite often and that it is OK. Go figure. From what I understood best solution is mark all those ridiculous non-existing pages as fixed and bot will sort them out by itself.
I did that, also I removed all redirects I made before (which truly never made sense to me), and it seems to work.
Solution is quite easy than, but still unnecessary work for nothing.
Guys thank you for all your help. I hope my fix is correct and that it will help those of you who need it.
