why is my computer running hot since i installed a paid version of Avast? it’s outrageous
You have posted in the ‘Avast Server Protection’ forum, so I’m not sure that this is the correct sub-forum.
Some information of your system might help, Laptop/desktop system, Operating System, CPU, RAM.
Have (or did) you another Anti-Virus installed in this system, if so what was it and how did you get rid of it ?
What are you doing whilst the system is running hot ?
In the Task Manager is there a process that is using a high CPU % ?
