antivirus for online scan

If you’re not ready to invest and/or install a good, full-fledged antivirus software program, there are two other options you can try that are made readily available – free antivirus or free online scans.

An antivirus for online scan may not be a truly free antivirus, neither will it provide further benefits, but it will at the very least let you know of any potential threats or those already lurking in your system or network.

The difference with the free trial or free editions of antivirus software is the antivirus for online scan executes its work on a server on the internet.

Online scans are done differently depending on which antivirus you decide to use, as some you can do online, while others let you download and scan for free.

Here are the most popular free antivirus software for online scan:

  • Bitdefender
  • Panda Security
  • F-Secure
  • Kaspersky
  • Norton
  • ESET
  • Trend Micro
