Remember to update your anti-spyware, anti-spyware, and all software weekly to fix bugs, and protect your PC against the latest threats online. Also, scan your computer atleast once a week for viruses, and anti-viruses.
The best way to prevent online viruses, and other bad software is to not download shady programs, and files or visit websites that look suspicious like shady adult entertainment, file sharing, and gambling sites. “Stay alert ,Stay safe”
