and yes, it prevents me from connecting to the internet, since most non-college routers dont reach into the center of campus, where i would connect to it
Like I said, it's either a virus redirecting your DNS or you may have some factory bloatware causing the problem in which case the bloatware needs to be removed.

Running a virus scan would be my first option, malware bytes is a good place to start.
Malwarebytes : Free anti-malware download
Also if it is a virus that is redirecting you. You should check your host file. Anti Virus programs don't check this.

-C: drive
-host (open with notepad and post a screen shot.

malwarebytes said everything's fine

and the hosts file looks ok, i think

# Copyright (c) 1993-2009 Microsoft Corp.
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
# For example:
# # source server
# # x client host

# localhost name resolution is handled within DNS itself.
# localhost
# ::1 localhost AFS
