Viruses, malware and other malicious bugs are hazardous to computers, files, and important documentation. Protect valuable data and keep computers healthy and infection-free by using simple and efficient online computer virus scanners at no cost.

Web-based virus protection differs from other virus programs as no download or installation process is necessary. All scans take place in real time, on the Internet. Online virus scanners offer varying degrees of protection and scanning, depending on which scanner is chosen. Some scanners check computer’s memory, files, folders or boot sectors. Several provide options to clean or delete infected files, while others offer no removal or deletion.
