Computer Help and Support

There are some free anti-virus programs available. One that comes to mind is AVG.

I use Symantec anti-virus, which is not free, but my work allows me to use it on my personal computer because I connect to their network and so they provide it to the employees for free.

Before you install any other anti-virus program, you should first uninstall the McAfee.

Good luck! (and always be conscious of things you are clicking on) If you ever get a pop up saying your computer is compromised or has a virus, and there is a phone number to call DO NOT CALL. Shut your computer down and reboot, it should go away (unless you go back to the website where the popup originated).

Microsoft will never have a support number for you to call if you have a virus, that specifically is a scam. They might get you to allow them to connect to your computer, have you log into your bank, order some kind of security from you, then later come back and offer to refund the money (faking a refund with your online banking, returning too much money, then asking you for gift cards to pay them back) It is a nightmare. They particularly victimize older people.

When in doubt, don't click on it.
