How Can You Spot Viruses Getting Your Computer?

Lol obviously if you are asking this question then your computer has to be doing something you not used to. Tell tale signs of a virus infected pc is is slows down tremendously from what you have previously known it to be. Another sign is if everything is awfully quite but your Hard Drive seems to be working up quite a storm although you aren't doing anything. Don't confuse this with your anti virus scanning your Hard Drive. Another way to check is right click your task bar and go to task manager. Click on the performance tab, if your CPU performance is spiking whilst your system is idle, you're infected, again, do not confuse this with an anti virus working in the background. Hope this helps:)

If you have an antivirus installed mostly it will notify you, or if your comp starts behaving abnormally
