I uninstalled Norton on a friends machine because I told him NOD would make his machine feel much faster. His Norton was updated and all... He was a bit sceptical about switching to NOD32 because he had never heard about it before. After NOD (trial of course) was installed I updated it immediately and was going to check if his graphics drivers were outdated so I was just going to open control panel and bam!!! Virus alert! NOD32 said the file was infected, I deleted and clicked on another icon and another virus alert again. OMG I thought, he must have lots of viruses I thougt so I ran the on-demand scanner and scanned trough his entire HD and it found 12 trojans and 2 viruses!!! One of the trojans were also visible in taskmanager, so I had to edit the registry to prevent an error message at startup after the trojan was deleted since it was configured to start at windows boot-up. After this I'm very happy to have NOD as my primary AV, I've seen Norton screw up before and now even once again. Thank you ESET for making an excellent AV!
