Hello everyone. It's been almost 1 week and I am having a few problems with my desktop pc. Which I never had any problems before. I will list the following problems below. 1...I used to be able to watch youtube videos now I am Unable to watch any youtube videos. Getting Errors on the screen (This video is currently unavailable. Download Adobe Flash Player.) 2...Try to download Adobe Flash Player and I get this error message (Unable to load application configuration.) 3...Try to download other programs or whatever and I am not able to. Such as trying to download Ad Aware and I get this error message (Installation Package save error. Please, check your firewall and security settings and try again later. Same as Google Chrome I tried to download. 4...Unable to open up any webpage through Mozzilla Firefox. At the moment I'm able to use Internet Explorer to browse the internet (Which I ussually use Mozzilla Firefox most of the time but not able to anymore.) But not able to watch any video or download anything without getting any errors. If possible can someone tell me whats going on and if possible guide me step by steps on how to fix it. I appreciate it for your help. Thanks.
