Did you know that Free Antivirus software cannot be legally downloaded in business organizations? Most companies don’t realize this and proceed anyway with the free versions, with the Antivirus software manufacturers continuing to confuse the marketplace. By simply looking at the licensing terms, you will see that downloading these versions is illegal in most environments other than for personal, home use.
Not only are you illegally using software by downloading these free versions, you are also sacrificing important components needed in Antivirus support – essentially, you get what you pay for. You also get no support.
