Browsers and websites corrupted by v188.8.131.5261 in CCleaner Bug Reporting Posted July 8, 2015 So i've been trying to fix this.... After many hours reading/researching/screaming... i understand that i have some kind of virus. But NOTHING catches it - superantispyware/malwarebytes/norton/avast/etc. So i've done a fresh install of Win7x64, followed by ccleaner 507. And everything is fine. So i guess it wasnt ccleaner. its so weird. i just cant figure out how or what started all the mess. oh well.
