Sirefef-PL virus

Hi there,

I believe my laptop is infected with the below threat:

Threat: Win32:Sirefef-PL [rtk]

Strangely, it started with a call from my internet provider saying that one of my home devices is infected and that they will disconnect my internet connection if I don't take action in 48 hrs. I came home, ran the avast and mbam scans and found that the laptop at home was infected with the above virus. Below is the sequence of events:

- Ran avast scan, tried to remove the threat

- Ram mbam scan, tried to remove threat, asked for a reboot

- At the start of the reboot, I got the virus threat notification

- I skipped 'scan' prior to/ during boot as I don't know how that will go

- Once in windows, ran mbam again. No threats found

- Ran avast scan again, same threat along with few others showed up

Any help getting rid of this would be greatly appreciated!

Thank you.
