I am running Win7 Pro Service pack 1 64-bit. I was trying to download an attachment, a PDF, sent to me wia my yahoo mail. I use the web interface for Yahoo, and it tells me that the file can't be downloaded. I go to Bleeping Computer to try to download malwarebytes (mbam-setup.exe) and when I click on the link, it asks me if I want to run or save. I select save, and it downloads the file, I see the % downloaded climbing, and it looks like it hit 100%, and then the box at the bottom of the IE9 browser window says mbam-setup.exe couldn't be downloaded. Does not seem to matter the file type, they all end up saying the same thing, XXXX couldn't be downloaded. If I select the retry button, the banner flashes, but says the same thing. I checked in Internet Setting, Security, and made sure File Download is checked. I even upgraded to IE10, and had the same issue, so I reverted back to IE9. Any thoughts on what is going on, and what I can do to fix it? Thanks in advance... Also, I am running Norton Antivirus 22.214.171.124, bt have turned off real-time scanning, and still can't download.
