Avoid at all costs
I tried to view a file a client sent me and this programme just started installing itself on my computer. No question about whether I wanted it, no question about which drive to install on or whether I accept their terms and conditions, just forced itself upon my pc. It set up tasks in task scheduler, auto-run at start-up, pop-ups every 5 minutes asking me to upgrade and subscribe. You know what other programmes do this kind of thing...viruses and malware. Avoid at all costs.
