[SOLVED] My pc became very slow after i accidently downloaded a virus

[Staying_Positive]

A few days ago I downloaded a program called "restoro" on my pc, which was instantly detected as a "trojan.multi.brosubsc.gen" virus by kaspersky. In orded to get it deleted I had to restart my pc. I ran multiple scans using kaspersky and malwarebytes afterwards and they didn't detect anything bad. My problem is that my pc became significantly slower ever since I restarted my pc to delete the virus. I tried restoring it to factory settings, but that didn't help. Any advice on what i should do to fix it/ is fixing it even possible?


I'm using a Lenovo Legion Y540-15IRH-PG0 laptop, which I've had for 6 months.

Specs:
INTEL CORE I5-9300H 2.40Ghz
RAM:8gb
Nvidia Geforce GTX 1650 4GB VRAM

Do you have restore points available? (accessible by typing 'restore' in search menu select 'Create a restore point', then click on 'System Restore' within to view your available restore points...; if some show up from before the infection, choose the most recent known to be from before your installation of the malware)

I had a restore point from 1 day before I got the virus. Tried using it, but I got a blue screen during the process, my pc turned off, and when I turned it back on the automatic repair begun. I didn't lose my files but the restore point isn't there anymore

Wipe and do a clean installation of windows. Hopefully that would fix it. Otherwise the damage is permanent.
