Please, someone help me figure this out. I have tried everything from using different file types to using different internet browsers. A few months ago I had a serious CryptoWall 3.0 infection. Thanks to a very helpful person on this site, I was able to eradicate the virus by using a number of different softwares and virus protectors. However, ever since then, anytime I go to a site that uses an HTML editor, for example Tumblr, creating a website on Wix or uploading images for a listing on Etsy, it tells me my image is not a supported file type. I have used ALL file types, so please do not offer this as a solution. However, if I upload an image to Twitter, deviantART, or an email, it works perfectly fine. According to a route scanner that Tumblr support did, something on my computer is blocking the upload of the images. I have tried disabling all of my anti-virus software, as well, and that doesn't work, either. How do I fix this? I am an artist starting my own business and I NEED to be able to upload images to promote my own work. Please, someone help me. I'll tell more information should it be needed and asked for. I'd love for one of the helpers on this site who knows their way around a computer to help me, as I'm out of ideas. Thanks.
