Compaq Presario CQ60-420US
a very old PC. 7 years is not too bad, on the edge there.

what OS? windows what?
doing what what are you doing.
my guess is this is BROWSER question,
is this IE , 4,5,6,7,9,10,11
only IE 11 (if is MS class) works now, so .... what is yours that?
web sites now block older IE versions a fact.
I use firefox v56, so should you.
back to internet explorer why>
you have browser take over, infections (google bar is one)
its infected, for sure.
get Firefox v56 and run that, or newer.
there are 20 top browers and IE is not in the lest.
IE is dead now at MS. 100% dead. Edge is NOW .

if running XP or Vista and using IE you will get nothing but pain
from now on.

this PC came new with (options day 1)
vista 32
vista 64
W7 32
w7 64
if vista you are doomed.
if W7 ,get IE11 from ms and use that
in fact IE11 is required to do MS updates, or they fail
are you running AV ? antimalware? even defender?

did you upgrade to w10 mid 2015 to 2016?

never post software questions, lacking OS name.
and what browser you use.
or answers will be wrong. I promise.
