i am not much of the computer

i am not much of the computer wiz but my security system did pick up a little something that caused the little tray on my desk top to go away(i have xp) and well, it was fixed. im still doing a last minute scan to make sure everything on here was COMPLETELY elimated from coming to my CPU again(so far so good). i used this antivirus system *am i allowed to name it or will i get in trouble?*(it might have to be payed for *sorry*). its a legit system because its been in business for an amount of years that it even tracked down the old version of the same software but of what u are witnessing here(it was like 2001 or something). anyhow, i believe it will solve a great precentage of the problems. im not saying that u HAVE to buy it or anything, but it worked for and i believed it only because a family member of mine told me(who could u trust better than family=). all in all, it will remove that pesky wallpaper and clear up the same pop up over and over again.
