Liam.exe virus - I tried the link posted earlier, it tells me to ring Tech Support Line on ( a Liverpool number) h

I think I have the Liam.exe virus. I tried the link posted earlier to MalewareBytes... But a message came up saying

"Windows defender might have detected an intrusion in your C:\Windows \  Ststem32 \ DII. All attempts to block this intrusion might have failed, Hence system is halted to,protect you from Identity theft or any loss of personal information.

Please contact Tech Support Live at [Removed] (a Liverpool UK number I think).

HOW do I know this is a genuine number I can trust to help me please?

Or can you give me an alternative link please?

Many thanks,
