Hi,
On scanning the network scan, ( i use computer and mobile with wifi router), my dns server was said to be compromised with remote hacking and as a solution, avast recommended the change of dns server to google dns server 8.8.8.8 and 8.8.4.4. I was then using auto detect settings of the router)I scanned again, and it says that it is problem free. Now, as i experienced loss of network, i just changed to auto detect settings , and now the scan says everything ok.
My question is how change of results occur one time as infected and next time as Ok. Is it that the time of scan of computer at that time has anything to do with the results.
