Before you all go like "it's malware!", please read on..

I'm using a school laptop, which means the administration has at least some kind of access to it.

Not long ago, I uninstalled Trend Micro antivirus (or whatever the name was..) because it seemed to cause a lot of slowdown and annoyance, and since then, explorer.exe has been using 50+ % of the CPU power while on idle.

I'm suspecting that there is something running in explorer.exe that tries to connect to an IP that doesn't exist, but I'm not sure.

I'm using Ad-Aware Free internet security, and I always keep it up to date as well as I regularily perform a scan. I also have ZoneAlarm firewall and Malwarebytes' Anti-Malware installed.

What should I do?

Since it's a school laptop...I believe that you should take this up to the IT point of contact there.

He/she has the responsibility for dealing with such situations on school property, IMO.
