Two is better than one. Well that’s not always the case when you have two wives or antivirus. Most computer experts would not recommend you to have more than 1 antivirus because they are not built to work with each other as antivirus nowadays are very sophisticated because they need to protect themselves real time from being disabled by viruses. If your computer have no problems in running two or more antivirus, then I’d say that you’re lucky and I pray that you won’t end up not able to boot up Windows one day.

However, some antivirus are made with multiple antivirus engines which will not conflict with each other. Most of the time the antivirus company will only say they use “multiple” engine but never say which antivirus engine. As far as I know, F-Secure, GData, eScan and TrustPort uses multiple engines. Using multiple antivirus engine can surely catch more virus but also reports higher false positives. Maybe using a multiple antivirus engine to protect your computer real time isn’t such a good idea but it’s a whole different story if you use a multi AV engine BootCD to scan a computer infected by virus.


If you have a computer that is infected by virus and it is causing Windows to run very slowly or even if Windows is unbootable, you can try using G Data BootCD to scan and clean the virus. Good thing about using G Data BootCD is it has two antivirus engines which is Avast and Bitdefender. Although they never say what engine, but I know when I checked the ISO image and there are avast and bdav folder in a dbase folder.

This GData BootCD is based on the latest G Data Antivirus 2010. It supports updating of the virus signatures and I suggest that you always try to update first before scanning because the latest version of this BootCD contains BitDefender definition dated on 14 January 2009 and Avast on 30 July 2008. Unfortunately the database cannot be retained and had to be redownloaded again the next time.

You can also get to configure some of the options by clicking the Options button at the top right of the program. There is a selection on which antivirus engine to use, the action to take when a virus is found, file types to scan, enable/disable heuristic, check for archives, check system area, and also setting the maximum size of files and archives to ignore scanning.

On my desktop computer running Intel Pentium D 2.8GHz with 2GB of RAM and a 200GB 7200RPM hard drive, it took 53 minutes 42 seconds to scan 88307 items. It’s pretty slow but I am sure it is very effective in detecting virus.
