DNS lookup failed
wew! i just tried yesterday to install a Kapersky Lab 2012 in my netbook and while installing it remove my MSE,i change from MSE to Kapersky because i was not satisfied with the results of MSE when someone inserted a 4gb usb stick and i suspected it right away it contains malwares,while scanning i saw a lot of ".exe , .pif" ..and i know those wer not part of her files because she didnt even care what was it and the results where NO THREAT detected ..my virus defintion is always updated and i also use a malwerbytes to recheck the scanning,but same results. >can anyone tell me why this WELL known scanners did not detect it?
and now after installing a Kapersky..when trying to activate a 30 day trial first,it says "FAILED" and when i look in my status of my network it works fine. and i tried in a browser i receive now a "DNS look up fail bla bla" i tried Chrome and Firefox and i suspected i was being contaminated with that usb stick..so i used the Kapersky Virus Removal Tool 2010 and Dr.Web..which was suggested in my previous thread.it detected a few virus and hacking tools which is "CloseApp.exe"..but after 3 hours of scanning..still i coundnt connect to any website,but my network status is fine. i can send and receive packetdatas..also run the ping 127.0.0.1 and ipconfig but everything was fine. .so any idea what is going on??

If there were viruses in your computer and now you can't connect to the Internet, then I would try two things.
Reset the Internet Options settings. Control Panel > Network and Internet > Internet Options > Advanced tab > Reset button at the bottom. I apologize if those directions aren't exact, I'm not on a Windows 7 machine at the moment so I am going by memory. I have seen where viruses will change the proxy settings which can cause problems.
Also, I have seen viruses affect the winsock so you can try resetting it. To do so: Run an elevated command prompt (Right-click > Run as administrator), then run the command "netsh winsock reset". After doing so, restart your computer.
