Hi, Pondus,
I am using only windows firewall with default settings.
Please explain this
If you have a ISP box with firewall, then a router with firewall, then a software firewall in our computer, when you run shields up it will test the firewall in the ISP box so the probe may never reach your computer
Could i take it, that it only probes the outer wall of the firewall, so the probe would not reach my computer.
Please also let me know, how wifi scans, does it scans with avast servers or the downloaded program of avast? It is not to question the scan of wifi, it had helped me overcome so such vulnerabilities. But if a doubt is raised, it may be for understanding the deep of the scan to understand further about it.
Thanks for your reply. So, online scans only touches the outer layer of your network and not deep scan of the router as wifi inspector does.
I was very impressed with wifi, that i have sent a router guidance doc to my friends in this regard.
To be more clear , could i take that avast is scanning , whether outside or remote sites could attack my router by using my LAN connection and router settings.
Please see the converted jpg of my doc and if it is small , pl zoom

R O U T E R A T TA C K S A N D SOLUTIONS
Hi, all of you might have seen the attacks on computer by wanna cry. It attacks computer OS , locks it and could be accessed after paying ransom. This attack is aimed at computer. But do you know that your router also could be compromised by the attackers using the ports genuinely left open default , for some remote assistance by the ISP or Vendor. Nowadays, this port is used by the attackers to know your computer internet activity without you suspecting any of it, because, it is compromised at the router level.
So, if you use personal computer, besides having best antivirus and malware programs, it is better to check your router also for any vulnerability.
In this case, I recommend, avast free antivirus, which is having a tool wifi inspector. Since it is free you could just install one time and then scan the computer with internet on. It will list all the connected devices and scan, and will give you results. If all is ok, you will get green , excellent remarks. If the scan finds vulnerability, it gives clue to what it has found and also the solutions.
The main vulnerability , I found in most routers is the admin password. Once configured, we forget about router, thinking that it is just a electronic device. But this is the gateway to your internet access as all we know. The routers admin user id and pw are one and the same. So, if a hacker could just guess, and do a brute attack, he could easily by pass those passwords. As a first measure, change this pw, and give a tough password by going to the router page, which all you know will be printed in the modem or using ipconfig /all command.
Secondly the dns attack. If your ISP sites are not secured, then there is a chance that it may give access to hijacked domains which will remotely control your internet activity.
If you are shown vulnerability in this regard, please go to the network settings and change adopter settings, then go to the adopter properties, ipv4, and then uncheck the obtain dns ip automatically to either google dns or open dns. If you change this, the router dns will be by passed by google dns which is safer. You cannot do any internet activity without google .
Next is open port vulnerability. The port 7547 is left for your ISP to communicate remotely. But this open port is now used by attackers to access your net activity, sometimes, changing the url of your router tr69 configurations for remote access at their end.
I have scanned with wifi inspector, and I was given alerts on the three major compromises, like weak pw, dns hijack, as well as port 7547. Normally for each log in , you are given an external ip by the Service provider, thro which your internet communicates. This shoud be not known. If some ports are open, this ip address could be accessed by the attackers.
I like anybody do not have tech savvy methods to safeguard, but the scan by avast wifi inspector prevented possible attacks and in this connection I am giving you my advice.
Please free to write to me for any thing, that I could help in this regard.
I also did not know what is the router page and settings etc before going thro all the scan results. If you do not want to go to the router page to change, it is my best advice to change the admin password, (please keep it safely to get it if you forget or want to open the router page. ) Normall passwords for any router are available in net pages.
I give my ideas to you, it is up to you to safeguard or leave it at that.
I am not Ask Leo, to give you technical tips on security, but my tips if it saves from router attacks well and good.
There are some more tools available in the net , but scan thro avast is safe, to my knowledge.
