I am having trouble uploading pictures to a website, icanhascheezburger.com. I used someone else's computer to upload to the site with no trouble, so the trouble appears to be with my computer. The first thing I tried was to switch from Comodo Pro to Windows Firewall while I was uploading. I was able to upload for a short time by doing this, like four or five days. But now I am unable to upload again, and I haven't changed anything in those few days as far as adding a new program to the computer. I have tried disabling any firewall--I know, not safe, but I was getting desperate for a solution. I disabled my antivirus, Avira. I tried using Firefox. I do have other security programs on my computer to use for scanning and to use for monitoring. Could one of these programs be the culprit? I don't understand why I was able to upload for a short time and now I am back to the same problem. If anyone has suggestions, please help me! Thanks!
