Is heating due to antivirus ?

[Rahul_18]

 My new PC came with trial subscription of McAfee antivirus for 30 days. When it got over I installed Kaspersky Internet Security. Though I'm unsure of a causal relationship but I have noticed that since then when I work on laptop with charging on it heats up and I can hear the sound of the fan running hard. Could this be because of Kaspersky or is McAfee antivirus better suited to HP architecture ? Please advise if there could be some other reason for heating up.

With a Win10 PC, you're going to experience a variety of problems not typical of the older PCs. Unlike with older OS versions, Win10 FORCES updates and patches on folks every week. This can cause problems not seen in the older OS versions.

First is sluggishness. You may experience a very slow PC at times because Windows Update (WU) is hogging your PC, searching for, downloading, and installing updates -- to bring your PC up to the most current version of Windows. This can also contribute significantly to high processor temperatures, as it is being heavily used.

Second is fan noise. That's directly related to fan speed, which is the result of processor heat, and WU is known to drive up the processor load -- sometimes to 100%. That can cause the fan to run loud and continuous for some time.

Third is disk usage. WU can easily force the disk usage to 100% and and keep it pinned there for some time. That's because it writes WU files to the drive, then it turns around and reads them, then it overwrites existing Windows System files. All of that takes a lot of disk usage to complete.

These processes are compounded by Win10 because new Win 10 patches coming out nearly every Tuesday. Since you can't stop Updates like you did with Win7, this means you're going to get updates, regardless of what you do.
