Once again, I feel obligated to strongly suggest that you protect your computer with not just anti-virus software but crapola protection as well. The often overwhelming deluge of crap that hits your computer daily needs to be addressed. Ad-Aware by Lava Soft seems to do very well catching the crap and asking if you would like to flush it. They update often and it plays nicely with others. I have had no software or systems conflicts with it. Check it out, there is a Free edition. Beware of sound alike and look alike competitors that are not Free.
Life is complicated enough without getting into hotwater with federal agencies so: TAKE NOTE Many things I review I got at no charge in exchange for an honest review. Consider this as informing you that ALL things I review may have been gotten at no charge. Realistically about 60% but in order to keep things above board just assume that I got the stuff free. Words like, “sponsored,” “promotion,” “paid ad” or even just “ad” are clear ways to disclose that you’re being paid to share information and links so BE AWARE that some of what I write can be described as an AD by the government. BTW I will NEVER say a product is great, super or even acceptable if it isn't whether I got it free or NOT!
