I spilled a cup of coffee on my key board last week and that was the end of Vista. New machine and widows 7. Hey guys is norton 360 any good?.
Sorry for your problems. Actually Windows has an excellent security program built in, Windows Security Essentials (MSE).
MSE is free, and MSE is, in fact, very good; there is pretty much universal agreement on that point. Is it as good as McAfee or Norton (Symantec) or other paid products? That is a matter of debate, but it is at least "in that league" .... and I would go so far as to say that it's the best FREE security software.
As to the paid products, I and many other (but not all by any means) professionals believe that Norton Internet Security (NIS) is currently the best of the paid products. Some people are very down on Norton, because mid-decade Norton had gotten very bad, but the Norton products since about 2008 are among the best of the security software products (note I say "among the best"; arguing which is THE best is like arguing about religion or politics ... you won't get a unanimous opinion).
I do think that, generally, having a fully updated (e.g. critical updates) system and MSE is definitely "good enough". If you want a paid product, I'd personally go with NIS. My gut feeling is that it may be a tiny bit better than MSE, but for many people the "tiny bit" may not be enough to justify the fact that it's not free.
BTW, to get MSE, go to
Microsoft Security Essentials - Free Antivirus for Windows
Note that MSE requires activation and validation; it will not run on copies of windows that are not "genuine", and tests for this during installation.
I have been using MSE for almost two years, and have had no serious malware. BTW, I use Anti-Malware Bytes to get rid of the toughest stuff. So far, so good.
All the best,
