All 100% of computers have viruses or spywares of one sort or another.

All Antivirus and Antispyware products on the market today cannot detect all viruses or spywares 100%.

Because of this, if your virus-scanner or spyware-scanner reports that no malware was found on your computer, how sure can you be that your computer is indeed 100% clean?.
The top 4 ways people get viruses on the Internet are as follows.

1. Using outlook express or downloading email to their computer rather than using a web based program like hotmail or yahoo email.

2. The second way is by using Internet Explorer as your browser. This browser is a spyware,virus magnet. Get mozilla firefox instead

3. The third way is by visting sites that have adware installers and such. Sites that offer free software or mp3's are the worst villians. Stay away from those sites.

4. The 4th way is by downloading mp3's It is not the mp3s that are real that is the problem but fake mp3's that are really .exe programs that add virus or adware or both.
