Totally Free Virus Protection

Free Online Virus Scanners


Free online virus scanners usually will identify a virus but not remove the threat. Some anti-virus software providers may require you to purchase their software before you can disinfect your computer. Other providers may offer a limited time free trial, after which you must purchase the software to continue using it.
