I also have the same trouble, with a little bit difference tho. I mean, I can open this web, heck...I can open most forums, search engines, FB, blogs, etc. but somehow, I cannot open some of my other bookmarks like deviantart, etc.
I already did what you guys been writing, the "-no-sandbox" up to download the clear ALL brosing data, cookie, cache, etc. and then I tried to download the tdsskiller...but the...scary thing happen here, once i unzip the file, my antivir (I'm using Avira AntiVir) gave a notice that it contains a malware...is it save to proceed?
nb: pardon my grammar ._.
