curios

hi folks i have a question.
about ten days ago i got hacked i am not sure how it happened but i suspect it was via skype i had left it open to everyone, anyway thing got so bad i thought the only way out was to reformat (i could not shut down or access anything i had to pull out the power source) i had a lot of things on backup discs so most of the work was the OS after getting back on line i decided to try a new browser and downloaded CAYMAN it works great and is faster than IE7 the only strange thing is that if i use it for downloads it just freezes the page and the only thing i can do is reboot,has anyone had a problem with this browser confused
