Infected - rundll32
Hello, once again I need some aid where my wits just won't suffice.
On my other PC, I installed windows 10 and Bitdefender as AV. Right from the start I was browsing process manager and saw 2 instances of rundll32.exe. It was suspicios to me since I've never seen the rundll to run as a process (at least not for very long). I terminated it and forgot about it. Today,however, I was away - when I got home I had a notification from Bitdefender that C\windows\syswow64\rundll32 is suspected as malicious process and blocked.(When I think again, the time it detected the virus is aprox. the time i turned on my pc, just didn't see the alert - hence it could be set to autorun) Yeah right, I checked the ps manager and there were 3 or 4 instances. Its a system file and only thing that comes to mind is that many migration modules inject into rundll. But I don't recall downloading or even running any suspicious files. Even if I did Bitdefender as one of the most toughest there that managed to detect my malware that went straight into memory - it would have alarmed me. How do I investigate this further? Any help is appreciated. Thanks.
