unknow links in website free generic viagra

Need a site link.

If you’ve been hacked, any idea how?

I am having this same problem. Yesterday a Cialis ad now a Viagra ad. It is located in my Heading area, directly under the logo, on only one of my pages. Please Help

my site is https://www.mystldj.com

i tried to install a backup and now all i see is a blank white screen. i am able to login to wp site and when i edit a page I see no test except red scribbly lines where i was thought to be misspelling. If I rightclick and highlight the area where text would be I see the text. Really lost at this point

update : this is what my host sent me after they scanned the files

Update my host has cleaned the files and site is working again. I had to purchase a service for them to clean the files (site lock)

hopefully this will protect me from getting attacked again.
