Hello, My problem started 2 days ago when i switched internet (from my parents house to my room close to school). Immediately these problems occurred: * Very slow internet (with moments) * I have to reload websites 3-10 or more times until i can view the full page * Downloading always stops at 99% * Images show half at the top, the bottom half is in another color, or moved to the side, blurry ... * Videos at youtube and other sides only show the black load screen, nothing more. * When i game, spectate mode always freeze, (when i play not) These are some possible problems i found, but i couldn't fix them with searching and trying on helpdesks: * SSL error -> ssl_error_bad_mac_read (on every webbrower (opera, chrome, firefox, IE) * Java is blocked because firefox says it is unstable or can damage my pc * I noticed this in my virus scanner (i use F-secure client security) : 24/03/2014 GEN:Variant.Kazy.257837 and on 16/03/2014 Trojan.GenericKD.1595555 , both removed by the virus scanner. I have tried many ways so solve the problem like: * Delete Cache, history, add-ons ... * Reset the modem * Full computer scan (twice) and no virus, spyware or malware found * Cleaned the pc with ccleaner * I have read most of the support mozilla pages to find a solution like checking my ssl- or proxysettings... * I have changed many things in options and programs (but changed them back when i saw it didn't work) I also took yesterday my pc to school to check if it would be better with another internet connection, the websites were loading faster (not like before but still better), but the image/video/download problem stayed (school internet = wireless, here with cable) I searched for info about a virus or trojan horse, but the only problem that was in common was a slow performance, not weird pop-ups or redirected to another site ... Everything without internet works excellent, so for those programs my pc is still very fast I hope someone can help me with this, if i forgot something important, i will add it. Brecht
