After doing a system cleanup, my PC unbearably slow and is unable to run most programs

I really have no idea where to start. I recently used Auslogic BoostSpeed to defrag and clean my system. I also did a Windows update shortly afterwards. After both of these were done, my computer became practically unusable. Every program I open takes forever to load and many of the programs will just refuse to respond. I have tried a system restore, but that didn't achieve anything. I have a custom build desktop for gaming, but it is rendered useless as I can't load a single game. Could it be a virus? I am just lost, as I don't know where to even start.

Hi

Virus or hard drive crashing as a guess...

All the best Brett

After doing a drive monitor, I've found that my HDD is bad and a failure is predicted. I guess I'm going to have to replace it if it's still under warranty.

The HDD was dead, I had to replace it
