I didn’t know how long my anti-virus had been expired but I know it had been awhile. 
Then I remember that CSUN students could get “free” (I use the word “free” freely because technically we pay for it through tuition, although it does come at a low price) anti-virus through the Information Techonology (IT) website.
If you just go down the left side bar to the Software Downloads tab and insert your CSUN login information it will give you a list of the software that you can download either to your PC or MAC.
The majority of the programs that are offered you can get free online, all except the Symantec Anti-Virus Corporate Edition which you can only download once.
Downloading your Anti-Virus is quick and easy, but if you don’t feel comfortable doing it yourself you can go to the IT help desk or give em’ a call.
