On my test computer, it took about approximately 25 minutes of deep scanning and found 30 infected files (deliberately placed). All the files were trojan viruses so all of them were renamed. The renaming process renders them unable to run anymore. The Avira AntiVir Rescue CD is a very good emergency malware and virus scanner and cleaner. It did a great job in scanning and removal of the malware and viruses. It is very useful in the virus removal of a system unable to boot due to infection.
