For those of you using AVG Free 2013, who have opted out of using the AVG Security Toolbar and Safe Search, you may occasionally get a pop-up in the bottom right of your screen asking you to use these features again. The top of it will begin with:
AVG Enable Web Protection for a better and safer Internet experience (free).
These features are more annoying than anything else. If you don't want them/don't use them, un-check the 3 check boxes and then click on Decline, to get rid of this pop-up.
You have probably heard about a recent security threat related to Java. This threat affected versions 7update10 and previous versions. It affected the browser plug-ins and not the Java program on your computer itself. A new update - version 7update11 - is now out. Download and install it. This fixes this latest problem. Note: when installing, un-check the option for installing the Ask Toolbar, as this is unnecessary and annoying.
Background Java is a background program that a lot of
web pages and programs use to run things. Unfortunately, malicious
software/viruses often use Java to run too. This has ALWAYS been the
case and is nothing new.
To stay safe while using Java, keep it up to date (when it pops up
wanting to update, update it). Check to make sure you don't have old
versions (in Add or Remove programs or Programs and Features). Remove
old versions of Java if you have any.
Also, regardless of the Java issue, you
should always make sure your anti-virus program is up to date and is
working properly and scanning your computer regularly. As an added
security level, I recommend installing the free version of Malwarebytes
and running a manual scan with it if you suspect you might be infected
by something that may have got by your main anti-virus program. User Behaviour You could have the best and most up to date security, but if your habits on-line are bad, you can still infect your computer. - Avoid bad sites that are infected (often Google and your anti-virus program will warn you when you try to go to one of these sites, but not always). - When you download a program or a file, always scan it with your anti-virus program (especially from a suspicious site (you can usually do this by right-clicking on the file on your computer and choosing to scan with with your anti-virus program from the drop-down menu). - Don't let friends, guests, relatives on your computer. If you do, run a full scan with Malwarebytes as well as with your main anti-virus program. Also, look for programs they may have installed and un-install them if you don't want them.
