I've been using that site for quite a while and all of a sudden, it gives me potentially dangerous pop-up ads saying my computer is not safe or something like that when I click the link to open the uploaded image.

Is anyone else experiencing this?

What is a good alternative website that doesn't have these pop-ups?

I'm worried I'm going to get a virus or something.

i haven't had a problem when i use it. but i don't use it often, because i use this site for all my uploading https://imgbb.com/ and its a really good site to use. 

I dont have this problem, and it could be your internet browser,  pc, vpn, or country your in. I've used it for years. Again theres other options like https://imgbb.com or even imgbox and making a website to host but also, alot of places have outsider ad pop ups that tell you this so you click on it and get a virus or "pay" to clean, not the sites fault necessarily as these ads can be placed via any site even google or netflix, etc;. Reccomend getting a vpn and ad blocker.
