The biggest database on Earth is definitely the Internet. It contains so much information that you can find almost everything in here. The major drawback of the Internet is that you can download lots of viruses.
And once you got your computer infected you'll have to put yourself through a lot of trouble to establish full functionality. Fortunately, the antivirus developers provide us with the necessary tools to reduce the infection risk.
And you can elect the right software, depending on the type of malware you have on your machine. Choose between antivirus software, spyware eliminators, anti trojan programs, firewalls, etc. The only catch here is to elect the right tool. I always thought that it is best to prevent malware installing on your computer than to eliminate it.
"avast! Antivirus" is an ALWIL Software product. The installation file will take about 11MB of the disk space. The version analyzed today (v.4.7.871) was released on August 8, 2006, so it is pretty "hot". The first "issue" of the software was released in 1988.

Internet Mail will provide protection for e-mails processed by other mail clients than MS Outlook and MS Exchange.
