In view with the latest Java security, it is a good idea to perform a quick security check on your computer. McAfee Stinger is my all time favorite standalone antivirus.
Also known as portable antivirus or USB antivirus, these antiviruses are ready to scan any files without the need to install onto the system. The reason for such a program is the need to a second opinion if one suspects that his or her primary antivirus is tempered with by a malware.
Pro and Con of Portable Antivirus
Portable standalone antivirus needs to be updated regularly; some antivirus allows you to download the database, while other requires you to download the entire software.

As you can see from the table itself, ClamWin Portable and Avira AntiVir Removal Tool appear to be outdated. Based on my own personal experience, I prefer McAfee Stinger due to the speed and size, HouseCall is good too; Kaspersky Virus Removal Tool is reasonably good too. I am not a fan of Norton Security Scan or Panda ActiveScan because they require the installation of plug-in or activeX onto your browser. Below are the links:
