Update,

Nothing showed up from the Malwarebytes scan as suggested, I did make sure the Rootkit scan option was turned on.

I have now attached the FRST log.

Avast anti-virus scan still shows Rootkit(s) found, plus many more warnings.

I’m thinking a fresh install of W10 may be the best option here, although it would be good to know what caused this.
Certain programs on my pc won’t open now, for example, Photoshop and Secunia PSI.

I’d appreciate anyone having a look at the FRST log, but please don’t waste too much of your time on it.
