There is no AMalum virus. This is a known false positive result from CA Antivirus which they should fix on the next update.
You might be able to fix your computer by getting the files out of quarantine, or else you need to do a repair with the Windows Installation disc.
I recommend http://www.datadefender.net if you are looking for an effective Internet Security or Antivirus program from one of the major providers. There are reviews, comparisons and links for the latest software from the main antivirus companies. I personally recommend Kaspersky Internet Security or ESET NOD32.
