I started using this site about 3 months ago as a new couponer. I noticed my computer started lagging closely after. The real problems began around 2 weeks ago when the computer just started shutting down after 20 min or so and giving a blue screen with a bunch of warnings about memory. When my two teenagers couldn't be without a computer anylonger I finally took my tower to a computer repair tech and the first thing he said was coupons.com " coupon printer" was the culprit. It comes with a lot of viruses and spyware. He quoted me $150 to fix. However since I did not have $150 on the spot, hence the couponing, he said that I could try uninstalling coupons.com "coupon printer" to see if I had any luck. I came home and did exactly what he said. I restarted my computer and ran a full virus scan. McAfee ended up finding two viruses and two Trojan horses. I couldn't find them before because the computer would not stay on long enough to fully scan. I am just going to go old school and get my coupons strictly from the newspaper from now on. Coupons.com needs to get it together. This site caused 2 weeks of headaches, irritation and frustration for my family of 6. I would steer clear if your family depends on the computer for school and other business needs.
