I did this FRST Fix and I think the temp data was removed and recycle bin was emptied too, after creating a restore point. I am attaching the Fixlog.txt with this reply please check that. when the PC did a restart it was still acting the same as before, opening TM reduces the cpu usage immediately and also i forgot to mention earlier the same happens when I do a scan with malwarebytes and security task manager, it'll increase the usage suddenly and then if i dont do any of these the usage will remain constant, spiked, and as soon as i do open TM or scan for viruses from any app it reduces, i thought it was malware elex.shrtcln, but now i think something else is causing this. I dont know what I should do next.
