If your computer seems to running normally and nothing seems wrong can you still have a virus or spyware on your system? I’m running Norton Security on my computer and everything seem pretty good.
Yes you can still get infected with spyware or virus, the goal usually is to get the virus on the system without the user knowing or discovering it. There are hundreds or maybe even thousands of new viruses and spyware created everyday. Many viruses and spyware are discovered everyday in the wild and everyday antivirus companies are updating their virus definitions to protect your computer. But companies like Norton, Kaspersky, McAfee and other anti-virus/spyware companies are always playing catch up, it’s like a cat and mouse game.
So even if you are running the latest up to date virus protection program you can to get infected with a virus because there is that small time frame between the latest definition update where you are not protected from any of the new viruses that is why it’s so important up keep your anti-virus up to date.
This is also why you should download the latest updates from Microsoft for your Windows machine right away or a least have automatic update turned on because virus writers can look at the latest Windows update and reverse engineer the update to see what vulnerability or holes they can take advantage of because they know not everyone updates their machines right away.
