Fileless malware - AdwCleaner, MBAM and FRST logs.

[eternal1312]

Hello. My malware is fileless probably. It's undetectable by MBAM, KVRT, AdwCleaner, HitmanPro and ESET Online Scanner. That malware is hidden in several amount of normal files. It makes working on my laptop almost impossible. It's running very slow; internet connection too. I checked another devices connected to the same WiFi and I can confirm huge difference. Random cmd.exe (and powershell few times) windows showing for 1 second. Sometimes I didn't even have access to some files via process explorer. Strange files downloading on my whole C: drive. I'm 100% sure that my PC is infected. Can you help me, please? Have a good day everyone! :)

Your current DNS Servers: 192.168.1.1 

Please consider changing your default DNS server settings. Please choose one provider only

DNS is what lets users connect to websites using domain names instead of IP addresses

Pick just one of these 5 providers. And be aware that you need to modify 1 time for IPv4 & a 2nd pass for IPv6

• Quad 9 Public DNS  IPv4  9.9.9.9 and 149.112.112.112  IPv6  2620:fe::fe  and  2620:fe::9  (one of the best for most users)
• Google Public DNS: IPv4   8.8.8.8 and 8.8.4.4   IPv6   2001:4860:4860::8888 and 2001:4860:4860::8844
• Cloudflare: IPv4   1.1.1.1 and 1.0.0.1   IPv6   2606:4700:4700::1111 and 2606:4700:4700::1001
• OpenDNS: IPv4   208.67.222.222 and 208.67.220.220  IPv6  2620:119:35::35 and 2620:119:53::53
• DNSWATCH: IPv4   84.200.69.80 and 84.200.70.40   IPv6  2001:1608:10:25::1c04:b12f and 2001:1608:10:25::9249:d69b

Hello,

Malware seems to disappear. Cmd and Powershell windows don't show up and PC isn't freezing. Download speed on speedtest is the same as before, but websites and videos are loading faster. Here is Dr.Web log.

Thank you
