Hi mate,

There could be a few different things at play. What is the resources usage like when the system slows to that extreme? Are there any background applications running?

I would also recommend doing a further deep scan using reputable antivirus and anti-malware software as the current threat profile is unlike anything ever seen before. It’s caught out a lot of people before where they don’t think they have malicious software and actually do!

Cheers,

Trav
