As instant messaging (IM) rises in popularity, it has become the new way for viruses to jump from computer to computer. Consequently, it would be nice if your antivirus program was aware of your IM activity so it could watch for any suspicious activity indicative of a virus.
Configuration for IM in your antivirus program may be no more than a check box or two. Does the antivirus program watch IM or not? If it can, I recommend that you tell it to do so. (After all, you’ve paid for some protection, right?)
