If you suspect there’s something strange happening with your computer, try one of these free online virus scan and removal sites.
What Is An Online Virus Scan & Removal Site?
An online virus scan sounds like a website that will scan your computer. That used to be possible. Now, most web browsers run in their sandbox to prevent websites from accessing other parts of your computer. An online virus scanner and remover is a downloadable, small program that doesn’t install like a regular program. It’s an executable file that runs like a portable app. The app may communicate with the app maker’s site to get virus definitions or send the results to their servers for analysis. Once the scan is done, you can easily remove the program.
Why Use An Online Virus Scanner?
Think of it as getting a second opinion from a different doctor. Doctors are brilliant, but they make mistakes. Same thing with virus scanners. Plus they’re free. If you’re not paying for it, why not use it?
