I've been trusting the security of my PCs & Laptops to PC Matic for more years than I want to count. I've also protected my daughters and grandkids computers (using all 5 of the licenses.) To date, none of them has been infected with any virus, malware, or other crap. It has kept the drivers up-to-date, and the PCs running smooth and fast.
Whenever I've had questions for their tech support, they've responded within hours, not days.
$50/year is cheap insurance - Just get it!
