Really? Why? Are they just in for the money now instead of providing a safe service or what?
CNet is full of spamware in its downloads, avoid wherever possible.
Bring up your task manager and check Performance - how’s your memory usage, are you near capacity or do you have plenty of free memory?
The downloaded software were being distributed with installation wrappers containing all kinds of malware. I haven’t used cnet (download.com) for the last 5 years because of this. Even though cnet denies it, they were still distributing malware in 2015.

When you download software from CNet now, you have to very careful because they try to trick you into agreeing to install crapware... like advertising software, etc. They’re not going to give you viruses, but what they try to install is still annoying junk you probably don’t want on your computer.
