Something is eating up my Computer's Memory

[RustySpider]

I recently had my computer fully restored and even upgraded from HDD to SSD, but upon turning it on, I've found that something is using 2.5gb of my physical memory; 32% of my 8gb available.

This can't be normal, surely? Is there any way to fix it? I don't recall having this problem prior to the restoration, and one of the first things I did post-restoration was reinstall Kaspersky, so I highly doubt there are any viruses.

That looks quite alright, Kaspersky must be taking a chunk of it too.
