Apologies in advance for the lack of info, unfortunately I panicked and did not collect the info required, however, I also did not delete any files that I'm aware of being associated with ransome/malware.
A few days ago, whilst using Firefox 56.0 on an Acer 5920 laptop running Win 10, I wanted to use the Dogpile search engine so I thought I typed in www.dogplie.com into the address bar. What came up was ww2.digpile.(no sure what the extension was) and the page changed to black background warning me that my data was being stolen and I needed to contact them and if I closed the page the PC would be locked. Note: W & 2 and O & I are adjacent to each other on the keyboard so maybe I typed the address in wrong.
Unfortunately, I panicked and pulled the USB WiFi dongle out. I'm not sure what happened next, whether I closed Firefox and rebooted the PC or just rebooted the PC but which ever I did the PC and Firefox started OK and did not seem to have any issues.
I then ran several anti-malware/virus programs including:
Avast Free anti-virus
SUPERAntiSpyware Free Edition
All of which only found a few tracking type cookies.
Thinking the PC was OK I continued using it, however, I am now not so sure I got off so lightly as Windows Update was switched off and once switched back on it freezes at different places. I've run the Windows Update Diagnostic tool several times but it seems to repeatedly report the same results fixing the same issues.
I realise this forum is not for Windows Update issues but I guess I need to know if the PC is infected before I ask for help with the update problem.
Any help would be much appreciated.
