I just upgraded to Quicktime 7 from the following link: http://www.apple.com/quicktime/download/standalone.html Immediately following installation, I noticed that I was seeing a Quicktime logo with a question mark in the centre of it appearing on strange places / websites where I hadn't ever seen it before. Such as in ads completely unrelated. MSN news links, etc. A QT logo would appear above the image or text... or off to the the side of it as thought it were acting as a sponsor even though it clearly didn't belong. Than it happened - I started getting pop-ups with this same Quicktime logo attached every couple of minutes. It wasn't so bad at first, but every time I clicked a single link to a webpage or whatever, a new browser window would open to the following site: http://imagecache2.allposters.com/im...ters.com/link/ Than, they started coming in more frequently. They all appear to be opening on the url I posted above! It's getting out of hand now... I just had to struggle to shut down 6 pop-up browser windows prior to posting this message, that were all appearing at the same time! I fear this is only going to get worse and it's making browsing the web really difficult and a hassle! Can anyone please help me out?? I'm not sure if I should delete QuickTime or if I've somehow downloaded a virus or somebody is trying to access my computer, but I'd really appreciate any help in fixing this problem!!! I do a lot of online shopping and transactions through Ebay and Paypal so I'm concerned and would like to resolve this ASAP! Thanks in advance for any help you can offer!!
