There is a old saying that applies to these situations:
"if it sounds too good to be true,it probably is"?
There are numerous hoaxes and false ads permeating the Internet
that can fool even experienced users.The best advice I can pass on,is do not install anything without checking with another
knowledgeable source;particularly,if it claims to be FREE.
Watch out for the latest addition to this scourge called
VirusProtectPro which shows numerous false infections after
you fall for a FREE scan.It then requires you to pay-up to
remove them.Removal is a task only for experienced users.
Good Luck
Mr Security
