As noted in the PC Magazine post, software apps can be “updated” and end up so full of extras they get flagged as malware by antivirus tools. Helper websites can go from benign to spammy overnight.
It’s always a good idea to have up-to-date anti-virus software installed on your computer. And if it flags your favorite download tool as not safe, accept its judgment and use a different program.
The PC Magazine post is updated on a regular basis to reflect the latest safe choices. It’s a good resource to stay current.
