Vulnerable To Wannacry/DoublePulsar Attack Warning?
« on: July 01, 2017, 07:43:18 PM »
Hello.

My full System Scan was run automatically this morning but no issues were found.

I ran a manual Smart Scan to confirm this but it stated that 'Owner-PC' is not configured properly and there was a network issue that was a 'Vulnerability To Wannacry/DoublePulsar Attack Warning'  but that my router is problem-free.

1. What is this about and why didn't the full system scan detect this? Is this a false positive situation?

2. When I check my 'Notifications,' there is a link beside Smart Scan for 'Details' from a May Smart Scan but when clicked on, it starts a new scan instead of displaying a summary-Why is that?

1. A full scan does not run a Wi-Fi inspector scan which scans the router and other devices connected to the network whereas the Smart Scan does. I don't think this is a false positive. Have you ensured all Windows Updates etc have been applied to the affected PC?

2. Known bug.

Alikhan:

I do not have a Router-I have a cable modem attached to a home connection.

Long ago, my computer tech advised against installing any Windows Updates because they cause more problems than they claim to solve so I turned them off.

I have not noticed any pop-up warning issues, my computer has not become slow or crashed at any point, and I am extremely careful to only visit legitimate websites.

I should have mentioned that Avast and my anti-malware software are up to date, my Windows firewall is on, and Windows 7 x64 Home Premium is being run.

In the Stats for some of the ransomware variants window 7 is most vulnerable, followed by XP, then windows 10 and windows 8.1.
Quote from: Avast Blog
The top 4 targeted operating systems, according to our data, are (in order): Windows 7 (78%), Windows XP (14%), Windows 10 (6%) and Windows 8.1 (2%).

Please read the two links included below:
https://pc.net/helpcenter/answers/difference_between_router_and_modem
https://www.howtogeek.com/234233/whats-the-difference-between-a-modem-and-a-router/

Once done, it should be apparent your router is inside your modem.

You've gotten bad advice from your computer tech. 

This alert you've gotten from avast is an example of that and a hacker would able to easily find the vulnerability avast is alerting you to, and exploit it.

If you'd like help in fixing this and other issues, please ask.

The Wi-Fi inspector can also scan modems. I think this is not a false positive but rather the PC hasn't been patched with SMB update via Windows Update.

If you don't use Windows Update, you are missing out on all the cumulative updates as well as more importantly, the security updates.

3. Pondus provided a link to the Windows 7 x64 patch so why would Windows Update need to be turned on?   
Do you have avast update on, why?

1. I checked and the 'Ransomware Shield' was automatically installed during an Avast update so why is there still an issue?

2. Am I opening or saving the Windows 7 x64 patch file that Pondus suggested?

3. After rebooting, should I run a Full Scan, Smart Scan, or both to ensure that WannaCry crawled into the computer before the vulnerability was patched?

1. I 'still' do not understand why the automatically installed 'Ransomware Shield' did not fix this vulnerability.

2. Why can't I open/save the Windows 7 x64 patch file 'instead' of turning Windows Update on?

3. After rebooting, should a Full Scan, Smart Scan, or both be run to ensure that WannaCry did not crawl into the computer before the vulnerability was patched?

Can someone 'besides' Pondus please assist me?

Someone else helping you will still get you the same advice.
Just because you don't like what Pondus had to say doesn't mean it wasn't concrete advice.

Let's try this again:

1. I 'still' do not understand WHY the automatically installed 'Ransomware Shield' did not fix this vulnerability.

2. I READ Pondus' article and it states to install the APPROPRIATE MS17-010 update but then he stated to turn Windows Update ON instead-Which option am I choosing?

I ask because I was told that turning on Windows Updates creates more problems than it solves so WHY can't I open/save the Windows 7 x64 patch file 'instead' of turning Windows Update on?
