Hi, Asyn believe it not. I just added the url in general settings in the excllusion lilsts. now those sites are not red alerted . I think it is working. But let us see in the next week, whether it is alerting again.
By running smart scan once in a week, i am having a feeling that i am protected by avast in all the threats from all sides. If it shows any dns hijack, i will probe and then apply the solutions by avast.
It is not that much safe nowadays that router is the main attack , and i bookmark for alerts on router checks and am receiving daily about 10 new type of alerts and solutions.
I have changed the admin pw, but avast prompts weak password. Probing it further, i saw a user pw column. So, i changed the pw for user also.
Thanks for all the suggestions in this regard from experts and staff. If i do not know about nslookup, it may not be possible to find the exact cause of the alert.Once again thanks all
