10 Free Online Malware and Virus Scanners

Occasionally I find myself working on a computer that has some problems. Maybe its malware, maybe its viruses, either way…it mucking up the PC and just generally slowing things down. Has this ever happened to you? If you’ve surfed the Internet for very long, you’ve probably experienced this and/or you’re prone to getting something downloaded and installed without your consent.
