If I have both Norton and AVG installed and running on my computer, will they interfere with each other?

[Jen]

My comp had a phishing attack through Facebook and I already had Norton running on my comp, but then I installed AVG too, because I heard that Norton doesn't always catch everything. Will they interfere with one another and do I have to uninstall one of them in order for one of the programs to catch all the viruses? Or can I leave them like they are?

Of course they will. Actually, get rid of both of them and download either.....
Microsoft Security Essentials

Avira AntiVir

OUCH.

Choose one. Uninstall the other.

This is what a Microsoft MVP has to say about the subject. You may also want to consider reading her entire web-page on "How to prevent Malware". It is one of the best that I have seen.

"Never install more than one Antivirus and Firewall! Rather than giving you extra protection, it will decrease the reliability of it seriously! The reason for this is that if both products have their automatic (Real-Time) protection switched on, your system may lock up due to both software products attempting to access the same file at the same time. Also because more than one Antivirus and Firewall installed are not compatible with eachother, it can cause system performance problems and a serious system slowdown."

But to be honest, Phishing tricks the user, not attacks the computer like a virus does, an anti-virus is of little value agains a phish...Just use common sense and make sure that your browser's phishing filter is "on".

And NO program come anyway near being able to catch "all" the viruses.

Having 2 anti viruses will definitely make file access times at least twice as long.

Phishing is not an attack against your computer. It's an attack against people's naivety.

When you receive an email, never consider it to be truthful. You may at best consider it informational but should always verify important information by some other way.

Always try to avoid sending personal informations in an email, even if you know the person, because the email might have been sent by someone else and the reply information made to appear OK in common mail programs like Outlook Express.

Also never enter any personal information on a web site that you opened from an email. This is the most common trickery. The site you are brought to is made to appear very similar to the original site.

There are ways to know if you're on the right site, but the safest is to manually type the address in the address bar, or using a shortcut (if you have one).
