Hello,

I was just speaking to GoDaddy support for some issues with my hosting, the lady said that there is a malicious virus on my hosting and stated that they would charge to clean up each of the hosted accounts. The automatic malware removal will cost me 88.83 USD.

How do I even know, there is malware? She claims the infection happened in Dec 2015.

I don't know if I should believe her, feel she was just trying to upsell. Is any plugin you guys have or recommend to do the same?
