Pros: ESET NOD32 is light on system resources, as it promised. It has a clean interface, and is easy to navigate through. When I did a scan, it finished fairly fast, compared to some of my other security programs. Excellent heuristics (good antivirus too).
Cons: I had the program for a short time. I've received some update errors, and it would install updates as fast as possible when the program launches. But after 2-3 minutes, it would say that my licencse key was "incorrect," even though it was correct.
Pros: did a full scan with webroot anti virus and spyware and did a scan with my norton 2011 ..neither one found anything..then had to uninstall the webroot,,in order to install the eset...when i did a full scan esetnod32 anti virus 4 found three viruses
Cons: install with user name and password from website a pain even if you have a disc this i has to be done,,to ensure updates
Pros: 1. The interface is clean and straightforward(unlike Norton and Kaspersky) 2. It is light on resources and it has very few pop-ups so you may forget it exists 3. Very effective without many false positives
Cons: 1. It lacks antiphishing and a link scanner 2. It does not scan very fast
Summary: I bought this antivirus because I could not get on the internet, and was having other problems too. To register the software you have to go online, but I couldn't. I called customer support and they were wonderful. They helped me get online and cleaned my computer up. They were very polite and helped me through the whole process. The actual software is wonderful and I would recommend this to everyone. With all the support alone, it was worth every penny.
