No it doesnt. Ive used it for almost 2 years. Been virus free ever since. It doesnt like any other programs such, as Adawre, CCleaner.
One thing that pissed me off was that, when i bought it, I bought it for $20, Then when It came time renew (it was for sale at best buy for $9.99 at the tim) they wanted me to pay $50.
