Good to hear. The next step is to try to figure out what may be causing your issue. This can be done a few ways, but let’s try the following as the first step

Download and Install WPT
https://social.technet.microsoft.co...tall-the-windows-performance-toolkit-wpt.aspx

1. Click on Start menu
2. Type command to start searching
3. Right click on command prompt in list and select Run Administrator
4. Copy and Paste each the commands below into the command prompt

xperf -on latency -stackwalk profile -buffersize 2048 -MaxFile 1024 -FileMode Circular && timeout -1 && xperf -d "%userprofile%\desktop\highCPU.etl"

5. Let it run for approx 1-2 min
6. Then Press Any Key to Stop capture
7. This will create a file highCPU.etl on your desktop
8. Compress the file to a .zip file and upload to your reply

It looks like AVG antivirus is causing a lot of spikes. I recommend uninstalling it and using Windows Defender. Also may have some more issues with GPU driver. After uninstalling AVG perform the WPT steps above again and also run Process Explorer steps below.

AVG removal tool

Download Process Explorer
https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer
1. Save it to your desktop then run it.
2. Right Click and Select Run As Administrator
3. In the View Menu click on Select Columns
4. Check Verified Signer, Virus Total and Click OK
5. Select Options Menu and Check Verify Image Signatures, VirusTotal.com > Check Virustotal.com
6. Double Click on the CPU Column to sort by highest CPU usage.
7. (Highest CPU Processes should be at the top once sorted properly)
8. Wait approximately a minute
9. Select Save or Save As from the File menu and save SystemIdleProcess.txt to Desktop
10. Upload the file to your Reply

Ok. Used the AVG removal tool & it's telling me that I have no active AVG product in my system, but I do - it pops up periodically on my desktop, & it's listed in my programmes...?

I'll go ahead & run it anyway, but seems a bit strange.

Ran it twice (with re-starts) but AVG is still there:

I'll try with Crap Cleaner & let you know.

Crap Cleaner seems to have got rid of it. I'm just running a full scan with Win Defender before I go any further.

Since you have a Trojan we need get that removed first before any more troubleshooting. I recommend that you post to malware forum as I am limited on this kind of help and get it completely clean and then come back here if you still experience problems.
