I have several FREE browser ad-on tools protecting me from stuff like this:
AdBlock Plus - ad blocker
Ghostery - tracker blocker
Web of Trust - website reputation and review service
I also use Private Internet Access as my Virtual Network Provider. Right now, anyone looking at my encrypted data stream would believe, from the IP address, I'm in Houston, which I'm not. Costs $40/year.
Nod32-Eset is my antivirus scanner. It does it's job anytime my computer is on. $32/year although when this year is done I'm switching to the free Bit Defender. More info monthly.
I have two other free tools, Malwarebytes and Adaware, which must be run manually. Their pay-for versions have full time protection and problem interception.
I heartily recommend any of these products.
Ah, claim you are in Houston, but I bet it fools no one. What around the sites, pages, and programs you are using. I bet you'll see things that are relevant to where you are, to what you search for, etc.
