Windows 8.1
8GB of Ram

I'm troubleshooting a friends laptop and I'm having a hard time finding what the problem is. He reported a slow usage experience and slow boot up, at first I figured it might be start up services, then he sent me a screenshot of his "AV" detecting numerous malicious files, little did he know that his "AV" was malicious... you know those adware/spyware programs downloaded through third party installs..
I uninstalled it, put Malwarebytes on it, scanned it and it found only 2 items.. okay, well I thought I'd scan it in safe mode, I tried from typing in advanced startup options, it failed and gave me an error, I figured some malware might have disabled safe mode or something, I tried to enable Windows Defender and it also failed and gave an error, again, the work of malware it seemed.
I went into msconfig and booted into safe mode that way, it worked. While booting into safe mode for the first time, he told me of the scanning of his hard drive volume because of an error apparently, after a 100% completion he said it still loaded slowly into the login screen and also into the desktop, but it was running smoothly once inside. I went into Event Viewer and noticed that there were hundreds of bad block errors, which I suspected might be the problem, though didn't think it would be the cause of the extreme sluggishness. I did another scan with malwarebyes, nothing popped up, I did sfc /scannow, it found errors but couldn't fix, I'll try to get the logs, I did a chkdsk and it also reported errors but I couldn't open the log in Event Viewer for some reason.
I started safemode with networking and this time it was as slow as if it was a normal boot up. I used CCleaner for giggles, nothing.. I had to go and restarted it normally, this time he reported of an error of, " Windows fails to connect to System Event Notification Service" I looked it up and apparently it is the cause of extreme sluggishness with many users.
Tried netsh winsock reset as most suggested, nothing.
Currently, I don't have time to troubleshoot it some more and would like it if I could get some assistance on here.
I might do a system restore in the end if I can't find the solution, if not that, then I'll suggest...
(I slightly looked at the RAM usage in Task Manager and noticed it used 4/8GB, I'll look into that more as well.)
