Hi Chris,

I'm fairly sure you are running Mavericks OS X 10.9.5. You  obviously have not 
read the many responses Peter H and I have given WAMUG regarding this subject. 
There is a WAMUG thread back on 23 May 2014 -  Subject: Virus  

OS X viruses do not exist! 

If you do decide to install AVG Virus Protection for Mac... MAKE SURE you know 
how to uninstall it correctly if you decide you no longer want it.
You cannot uninstall these type of programs by dragging the application to the 
trash (as you can do with Mac Applications).
----
You are running Mavericks OS X 10.9.5? Please read thoroughly what my response 
I have sent to WAMUG previously. 
I've included it below again FYI. 

Do Macs really need Anti-virus protection?

/Quote:
OS X already includes everything it needs to protect itself from viruses and 
malware, and it's free. Apple recommends keeping your Mac updated with software 
updates from Apple. Refer to the links above, which apply equally to Mavericks 
as well as its predecessor.
 
A much better question is "how should I protect my Mac":
 
• Never install any product that claims to "speed up", "clean up", "optimize", 
or "accelerate" your Mac. Without exception, they will do the opposite.

• Never install pirated or "cracked" software, software obtained from dubious 
websites, or other questionable sources. Illegally obtained software is almost 
certain to contain malware.

• Don’t supply your password in response to a popup window requesting it, 
unless you know what it is and the reason your credentials are required.

• Don’t open email attachments from email addresses that you do not recognize, 
or click links contained in an email:
• Most of these are scams that direct you to fraudulent sites that attempt to 
convince you to disclose personal information.
• Such "phishing" attempts are the 21st century equivalent of a social exploit 
that has existed since the dawn of civilization. Don’t fall for it.

• Apple will never ask you to reveal personal information in an email. If you 
receive an unexpected email from Apple saying your account will be closed 
unless you take immediate action, just ignore it. If your iTunes or App Store 
account becomes disabled for valid reasons, you will know when you try to buy 
something or log in to this support site, and are unable to.

• Don’t install browser extensions unless you understand their purpose. Go to 
the Safari menu > Preferences > Extensions. If you see any extensions that you 
do not recognize or understand, simply click the Uninstall button and they will 
be gone.

• Don’t install Java unless you are certain that you need it:
• Java, a non-Apple product, is a potential vector for malware. If you are 
required to use Java, be mindful of that possibility.
• Disable Java in Safari > Preferences > Security.
• Despite its name JavaScript is unrelated to Java. No malware can infect your 
Mac through JavaScript. It’s OK to leave it enabled.

• Block browser popups: Safari menu > Preferences > Security > and check "Block 
popup windows":
• Popup windows are useful and required for some websites, but popups have 
devolved to become a common means to deliver targeted advertising that you 
probably do not want.
• Popups themselves cannot infect your Mac, but many contain resource-hungry 
code that will slow down Internet browsing.
• If you ever see a popup indicating it detected registry errors, that your Mac 
is infected with some ick, or that you won some prize, it is 100% fraudulent. 
Ignore it.

• Ignore hyperventilating popular media outlets that thrive by promoting fear 
and discord with entertainment products arrogantly presented as "news". Learn 
what real threats actually exist and how to arm yourself against them:
• The most serious threat to your data security is phishing. To date, most of 
these attempts have been pathetic and are easily recognized, but that is likely 
to change in the future as criminals become more clever.

• OS X viruses do not exist, but intentionally malicious or poorly written 
code, created by either nefarious or inept individuals, is nothing new.

• Never install something without first knowing what it is, what it does, how 
it works, and how to get rid of it when you don’t want it any more.

• If you elect to use "anti-virus" software, familiarise yourself with its 
limitations and potential to cause adverse effects, and apply the principle 
immediately preceding this one.
• Most such utilities will only slow down and destabilize your Mac while they 
look for viruses that do not exist, conveying no benefit whatsoever - other 
than to make you "feel good" about security, when you should actually be 
exercising sound judgment, derived from accurate knowledge, based on verifiable 
facts.

• Do install updates from Apple as they become available. No one knows more 
about Macs and how to protect them than the company that builds them.
 
Summary: Use common sense and caution when you use your Mac, just like you 
would in any social context. There is no product, utility, or magic talisman 
that can protect you from all the evils of mankind."
