This has been mentioned previously, but I noticed Virus Chaser has updated their Australian website http://www.viruschaser.com.au where a single licence is AU $29.99 (about US $27.43). Vista version is mentioned as available. Tried it out for a few days now and it seems to be very lean on resources, and provides a thorough in-depth scan (no false positives after a few days of scanning). No other problems experienced. Few questions, without a Virus Chaser vs other comparison. Does Dr Web still provide the virus signatures/engine for this software? Will there be an update in the near future? The 5.0 version was mentioned on here around 2005. The current version I downloaded is 5.0a. Anyone else using the program, and is it all running ok?
