Problem with the site. The ChatGPT website has been infiltrated by some fraudulent crap that pretends to be ChatGPT. It’s called Chatgptonline, it was added from the “GPT Review” section itself, I didn’t add it. He also asks to go to his website directly insolently. I use VPN FastProxy. Maybe he’s the one doing this kind of stuff? the site is quite suspicious, or it was someone hacked chatgpt, which is unlikely, so perhaps I caught a virus.

What I have already done:
Cleared browser cache and cookies.
Conducted a full system scan using anti-virus software (Dr.Web)
How to completely remove this extension from the browser?
What other steps can be taken to completely clean the system from possible infection?
Could this be related to the use of VPN FastProxy, and what is the best thing to do in this case?
