Virus on my vbulletin

[Toddola]

Many of my users are complaining on a tojan horse on my forum: www.mjoai.com/forum...

Can you please help, wtf is this, is this a vbulletin breach?

I hope I can get some answers, or my forum has to go down?

Can you describe more details of what exactly your users are experiencing ?

It's probably a server issue. You should talk to your host and also look at your access_logs to see how they got in.

I think its probably due to vBSEO. A lot of sites who havent upgraded to the latest version are getting hit by a vBSEO vulnerability.

It will insert an iframe in the header/footer template and direct your users to a malware site.
