i have had malware bytes for about 6 months now and it is great, however since this trojan has appeared on my laptop i cannot check for windows updates or update malware bytes. i last updated on jan 21 09 i have done a full scan many times and still cant get this trojan off my laptop. What do i do?
I found that if the “DNS Client” service is stopped the virus is unable to redirect DNS and you can update MalwareBytes. My Jan 2009 copy did not find anything but once updated it was able to find and clean this trojan in safe mode with networking.
hi even i had this DNSchanger in my laptop. try to disconnect internet and scan, or try SUPER Antispyware which i have used to remove the infection. then go to your IPV4 settingsof your network and reenter the settings to go into windows update
disconnect computer from any routers and run Malwarebytes’ Anti-Malware, then reset the router.
I had the same issue and finally found out that the dns was changed on my router. I would run malwarebytes and it would clean it up but it would come back because the dns on the router was rediecting my computer back to the infected sites and reloading it on my computer. I went into the linksys router and reset the dns so that nothing was in the boxes and then saved it and restarted everything and it works perfectly now without any problems downloading the updates from Microsoft and others.
Yes. I also found that my DNS had been hijacked. Even though your ISP may instruct you to leave your admin/password combo at the default settings, it makes your router completely vulnerable to nastiness. Change your router password, and revert the DNS to auto and the redirects and false infection popups go away.
thank you thank you thank you! Hopefully its out the system. But you are a godsend
