probably good all tracking cookies.. IF you click on a certain page while surfing, people can load your computer with spy ware... For more info go to www.wilderssecurity.com or www.wilders.org for their download pages. I would start with spyware blaster download. Its easy to use. "key loggers is another big threat these days. Thats where people can actually see the keys your keyboard types.. Basicly, If you click on a certain site per say.. It can deliver your computers IP address and if they have your IP address it is getting easier & easier to get your screen name. So we obviously visited a site & got spam unless DB knows something about it which I am going to notify them of my post & maybe they will reply ... and needless to say they will probably either move my post or better yet delete it.
***note this should not freak anyone out it is probably not virus related but just letting you know the possiblities but it is probably just spam
From somebody who knows how these things work & deal with them day to day
