I do use utorrent normally, but I downloaded the software from filehippo, and I do not use any form of public tracker to download anything, and I have used that particular version for a long time without any problems.
I am not using any usb stick whatsoever, so that can be ruled out
Anyway, I have now scanned with Malwarebytes, aswMBR, tdsskiller and they all report no issues, so far so good it seems the rootkit has gone, I just need to get Windows Firewall working again though.
"Windows Firewall can't change some of your settings.
Error code 0x8007042c"
any ideas? thanks!
