Hi AVG Community!
By Visiting Amazon Seller Forum, I get warning "infected by URL:blacklist". It also gives me an complicated code that I could not understand. Then it tells me that the threat has been secured and tells if I want to scan it etc. Due to this issue i am not able to access this website.
Please let me know how can I fix this issue.
