How to fix a link virus on a website?

Question

Malware

Hello! I'll describe the problem... A site on DLE, some kind of virus has recently appeared that creates transitions from menu buttons and other links on the pages of the site to another site, and this happens quite spontaneously.
Checking the hosting for viruses did not give any results. I didn't find anything in the files either.
Tell me how to fix it, maybe someone came across a similar one. Thank you!

Answer 1

Take a VPS tariff (you can take it for 1 month) where ImunifyAV antivirus, you may have to buy it for 1 month. Raise the site there and run it with this antivirus.
If there are forums, comments, reviews on the pages, it is better to delete them.
