Antivirus software is regarded as a "must-have" program for any computer. They aid in the protection of your computer against viruses, spyware, and other malicious software. There is no need to be concerned if you have a capable antivirus program installed on your computer.
But in case, if the virus or malware infects your whole computer then you might require a portable antivirus to completely clean your computer. These antivirus programs, like most portable apps, do not require installation on your PC. You can take them with you anywhere in the form of, say, USB drives and ensure that your systems are secure.
Best Portable Antivirus Software for Windows
