Hello,

A couple of months ago I unintentially downloaded malware via an executable. This caused lower performance, added a search bar to my desktop, and other various add-ons and extentions and browser redirects. Forgive me if I miss what all happened that day, but MalwareBytes and Avast were installed that day to run and clean my computer, as well as ending processes that were harmful and deleting them from their locations in Windows Explorer. Everything has seemed fine for the most part, and I had resumed normal activity with occasional virus scans to ensure everything was working normally.

 

However, it seems like ever since that day, my computer ran a little slower.

 

After getting frustrated today with Firefox seemingly running slowly and thinking that most performance issues are due to applications using more RAM, I checked the Resource Monitor to see what exactly was using up so much RAM. I saw that svchost.exe was using tons of this RAM, found the file location, and am unsure if this is a legitimate version of the executable. My worries solidified when I searched the file location to find Malware Removal threads, one even on this website.

 

I am new to this sort of thing, but if any more information is needed I will gladly provide it.

 

Thanks in advance for your patience, and hopefully I do not neglect or forget any important details.
