Confirmation the connection between VPN's sudden drop in speed to web disconnections and viruses

Hello Bitdefender lab

Because a few days ago, I stumbled upon the Dell computer USB RECOVERY software either can't find the windows 11 system online, or find the ISO file is only 800MB, and then because of the accidental installation of the OUTBYTE driver updater and update 10 drivers found that the network is often disconnected, I scaned my computer with gridinsoft anti-malware and found many viruses, I deleted a few of them manually. after OUTBYTE was judged as a PUP, the original system restore point in windows suddenly disappeared, so I had to delete it first. But yesterday, I suddenly found privado vpn on windows 11 and china android 13 so slow that I can hardly open the webpage, so I send the related files to you guys to investigate.

tdxcef.7z

The above two zip files are the same Chinese stock trading software installed in my windows 11 computer, the first one is a zip I made based on the first screenshot, and the second one is a zip of the original installation package from the stock company. The second screenshot contains all the files of this stock trading software except magisk.But Also bitdefender total security quarantines many viruses just not magisk, I don't know how to keep these records and samples or if they have to be deleted to be safe or on the contrary how to send them to you guys for further investigation if not sure.

Currently, I also found that if I let privado vpn reside in the background but not connected to the server in windows, I can't connect to China Telecom's wifi, and the internet connection is back to normal after I quit it. I asked perplexity AI, he said it's caused by a problem with outbyte's updated driver and need to reinstall the system. Moreover, many times in the past when the computer had system restore point disappeared and driver installation problem, China Dell didn't explain and solve the problem well, just changed the network card once.

I hope that without reinstalling the system, bitdefender experts can give me some better suggestions and guidance, such as installing some free third party software to help find the cause and solve the problem.

Best Regards

@Alexandru_BD Any thoughts on this issue? Thanks.

Hi,

It's not the antivirus that needs to solve this certificate issue. The connection was blocked due to a certificate mismatch. Notifications can appear whenever other vulnerabilities or malware is detected, to alert the user of potential threats. If a notification is critical to the security of the system, it cannot be disabled, but the source of the notification can be investigated, to determine what is causing it and to what extent it can be mitigated.

Bitdefender’s Online Threat Prevention module may alert you when you try to visit a secured website (HTTPS) with an invalid security certificate, or a certificate that doesn't match. It tends to be websites with lots of ads, such as news websites, and analytics companies with an expired certificate trying to establish a connection. If you wish, you can check their SSL certificates using the link below:

To resolve the issue you are facing, uninstall any unknown programs and browser add-ons from your computer, revoke Web Push permissions for the sites allowed to display messages on your screen, reset your browser and install an ad blocker. For detailed instructions, read – Remove adware, pop-ups, and browser redirects from your PC.

If you use an email client such as Microsoft Outlook or Mozilla Thunderbird, clean up your inbox by deleting emails from unknown senders. Delete all SPAM/Junk as well. Finally, empty the trash on your email account.

Should you wish to disable this protection layer (not a recommended action), you can turn off the Encrypted web scan feature. Open Bitdefender and go to Protection → Online Threat Prevention → Settings → temporarily disable the Encrypted web scan feature by setting it to the OFF position.

I hope this helps.

Dear Experts,

I have uploaded the scan logs as per your instructions for your records. Currently, Bitdefender is no longer triggering warnings upon startup. I suspect this is due to an activation adware program embedded within another Irish company's antivirus product. After removing it several days ago, the warnings ceased.

It appears that distinguishing between friendly and hostile elements is not as straightforward as it seems, for the shadowy assistants of Germany's Alternative for Germany party may be conducting illicit activities under the protection of safe houses.😊

However, for me, the overt schemes of Chinese mobile phones are more frustrating in the short term. I previously reported issues with the phone's security manager to customer service, but since my phone doesn't provide firmware or driver downloads, rooting it is even more troublesome.

Do you think it's better to use ADB (Android Debug Bridge) to remove some system apps, or is KernelSU, a root solution safer than Magisk, preferable?

Hi,

I'm not an expert on that, I must say. For future reference, the relevant logs should reach Bitdefender Support, because we can't analyze such files on the forum..

As for embedded/bundled adware, this is very common, as I've mentioned above. Note: having multiple antivirus programs running at the same time will not make your computer more secure. It may degrade performance and even prevent proper malware detection. So it's good you've uninstalled that one.
