Hello all, I have an annoying problem that prevents me from using my laptop properly. First of all, I get this error for every page I try to open in Google Chrome: "This webpage is not available The webpage at <any url here> might be temporarily down or it may have moved permanently to a new web address. Error 137 (net::ERR_NAME_RESOLUTION_FAILED): Unknown error." Secondly, no software can connect to the internet to update itself; for example, when I tried to update Malwarebytes, I got this error: Finally, from time to time I get an error window from BackupManagerTray (I think this has something to do with Acer BackUp) which states: “The TCP/IP protocol is not installed properly”. The first thing I did was to check if I actually have an internet connection - by using 'ping google.com' in Command Prompt, I discovered that I did. Afterwards, I tried to open Internet Explorer and surprisingly, browsing worked just fine - yey for me! As I had previous problems with malware and viruses, I tried to disinfect my laptop by using the following software: Bitdefender 2011, AVG 2013, Malwarebyes’s Antimalware, Kaspersky Virus Removal Tool (website version) and TDSSKiller. Some of them found several infections which were cleaned, but my problem persisted. I figured there must be a problem with my IP/DNS configuration. In Command Prompt, I tried to reset them by using ‘netsh winsock reset’(and similar commands), but with no result. I have also tried ‘sfc /scannow’ but it didn’t find any problems with the system’s integrity. I ran out of options and I really don’t know what to do anymore. If anyone experienced this or has an idea about what my cause this problem, please help me!
