Okay, so I was on a well-known streaming site yesterday trying to catch up with various tv shows, and I ended up getting infected with the PCEU ransomware virus which completely locked my computer with a screen demanding £100.
I rebooted my computer into safe mode with networking and downloaded malwarebytes, and performed a quick scan which picked up some infected files and removed them. I then rebooted into normal mode and was able to use my PC again; it seemed that the pceu ransomware had gone. However, I performed a full scan with mbam which picked up the Trojan.FakeMS which it removed. Upon rebooting again, I ran another mbam full scan just to be safe, and it picked up the fakems trojan once again, which I thought it had just removed. I then decided to restore my laptop to factory settings (complete wipe of the C: drive) as I don't have many valuable files on here. If it's of any use, I use a Samsung laptop and used Samsung Recovery to restore my laptop to factory settings.
My issue is this - my laptop seems to be working fine now, and is configured the same as when I first started using it. I have reinstalled my antivirus (Avast) and run subsequent mbam full scans, all of which haven't been able to detect any malware. However, I know that some malware is pretty clever, and can modify itself to disappear once it knows it is being searched for. I just want to be on the complete safe side, as I use my laptop for purchases with my card etc, so I want to make sure I am completely rid of any malware that may still be lurking in the system somewhere.
Is there any way to make sure that I have indeed removed all malware - any methods to check to be certain my system is clean?
Many thanks :-).
