Virus, worms and any other malicious codes will not be a problem if NOD32 is installed in your computer. We have tested it and the results have been really good, next to excellent.
We have detected other main feature, it is really fast when scanning and performing tasks. While other software took a long time scanning the HD, it took next to the 20% less time, so it is highly recommendable.
A good antivirus which doesn’t take a long time to scan your system, that’s great.
