Pros: Yes, you did get an invoice when you ordered it from newegg. Either print the email with subject "newegg.com - invoice" or log into your account on newegg and print the order summary from your account. Any document with the order date and price on it will work fine.
Cons: People who don't know what they're doing write reviews that don't make any sense.
Pros: Second time buying this program and decided to buy it again after the year was up. Great thing about it was the mail in rebate which made it free. Non intrusive anti virus with a light weight and clean interface. A good program to have just in case something bad turns up like opening an unintended email or program. Updates regularly on a schedule so no worries on that. several scanning options. allows a free upgrade to next year version of kaspersky if your still with...
Cons: The first time i did the rebate it took a long time so dont expect it to come right away. It is going by snail mail to arizona so unless u put it in a 2 day shipping envelope or live in the area its going to take a long while so be patient and wait for the check. i still hate the fact that i only have a year before contemplating on buying another one. even if its free.
Pros: I've been using Kaspersky since 2008. It's always been easy on my system resources and never lagged any of my games. Even when I don't have the gaming mod on it still allows me to play any game without disturbance. It's very good at updating in the background and when it does I don't notice it. This is because Kaspersky updates often so it does not have to download huge databases with new threats. I am very happy with this product.
Cons: Not the cheapest option, but you get what you pay for.
Pros: I have used this antivirus for at least ten years and have never, NEVER! had ANY type of infection or malware make it on to my system(s). I currently run this on 4 computers with Win7 and have no issues. Also, the product key works on updated versions. For example, I bought a 2012 3 user product about 6 months ago (free w/rebate) and did not install on anything until last week. I downloaded the 2013 version, typed in the key and viola', I had the 2013 version. In fact...
Cons: Too many warnings at end of license, a weeks worth would be fine for most. Despite these, I still wait wait until the last day. The rebates take a little time, but about typical for rebates. But hey, in the end it's FREEEEEE! Ok bean counters, actually, it's not totally free. There is the cost for the paper, stamp, time and the infintesimal lost interest on your money.
Summary: The most popular anti-virus software is Norton...It's the biggest hog of resources as well..who knew.. I switched to Kaspersky years ago and you do not know it's even on until you get a warning telling you that there is a virus in your email or in something you are about to download..It's kept me out of that frustration ever since I changed over..Love it .
