I'm not sure 100%, but i think it happened while installing the patches. Do you know if they have some kind of a support forum? I will try Qihoo again but won't install their so called "patches"If I understand you correctly, the problem was appeared after you use this "Patch" feature on 360 TS right? if so..I'd suggest try 360 IS instead since it's more mature and stable. My experience with this "Patch" feature was...my windows is up to date (the important not the optional one) when I scanned it with this "patch" feature it was detected some vulnerabilty patch, so I try to patched it (I created a system snapshot before in case it would messed up my system) after I patched it, my windows update was messed up, saying I never updated it before, but after I re-scan it...everything backs to normal, not sure what happened then I just roll back to my previous state before. I guess this "patch" feature is still on beta or something.
