Unfortunately, unscrupulous people will use sites like this to tell you to download this or that removal program, but the truth is that the virus will probably keep you from being able to use them - IF they work. Many of them will download and then tell you to pay for the service. They are just marketing a product. What I'm about to tell you is completely free and simple to do. It will not harm your computer either, but it does take an hour or two to do properly.
The AV Security Suite is a pesky thing that pops up all sorts of error boxes. If you try to run a virus scan it will tell you that the scan is infected. Everything that you do will result in a box telling you it's infected. If you try to look up information on how to remove it, it will hijack your browser and keep redirecting to porn sites.
The first step is to block the sites that AV Security Suite comes from. Go to Tools on toolbar (if it will launch), then to Internet Options, then Security Tab. Click on the red circle with the line through it that says, Restricted sites. Click on it and then click on Sites. Do NOT add the site that it shows. (The one that you are on now). Manually enter these sites into the box that says WEBSITES. I suggest doing this before you ever have symptoms of the virus as a precaution.

If you already have the virus you will have to restart your computer in Safe Mode. To do this, click restart and then keep pressing the F8 key until the black screen pops up. Use the arrow keys to highlight Safe Mode and then press enter.
Go to your Control Panel and go to Add/Remove Programs or in later versions it may say Programs and Features. Go down the entire list and remove all of the spyware and malware programs that you have added in the past and are not using. This is one of the placed that the AV Security Suite comes from.
To make the next step easier and faster, go to the search and type RUN. In the box type, %temp%. When the box pops up highlight it by holding down Cntrl and A at the same time. Right click one time and select delete and then confirm.
Type RUN again and type %systemroot%/prefetch. Highlight and delete these files as well.
Now go to your Recycle Bin and delete those files. (Hint: To keep you computer running faster you should do this once a week anyway. These are all of those pictures and files that you have been looking at.)
Go to Run again and type in MSCONFIG. Click on the Startup tab. Look for anything that says AV Security Suite and take the check out of it. This will disable it from the startup menu. You can also get here by pressing Cntrl/Alt/Del at the same time to get to the Task Manager, but with this affecting your computer it may not work this way.
Next, go to your search function and type in SPY and AV. Make sure that you select to see all files and extensions. If you see a file called AV Security Suite, DELETE it. Also delete any other spyware and malware programs you still see in the list that you are not actively using. Make sure to keep the program that you normally use because that is the next step.
You will need to launch you virus scan from its desktop icon. Do not be surprised if a big black box pops up. You are in Safe Mode and things will look different. You will probably click enter to get it going and then sit back for awhile until it is done.
Now, you may find that your Security System has been disabled by the program and you cannot turn it back on. This can be fixed. Go to the Search box and type SERVICES. A box will pop up. Services that are enabled will say STARTED next to them. If it does not, click on it and click Enable. You can now return to the Security Center and adjust your settings.
