Ironically on what has become known as Safer Internet Day, users of Bitdefender Antivirus are reporting today that the security software has suddenly stopped working. After installing an update, Bitdefender users are seeing errors that state "Bitdefender Security Service has encountered a critical error!" or "The Bitdefender Security Service (vsserv.exe) is unavailable at the moment" .

Both of these errors appear to be caused by a new update pushed by Bitdefender that has caused the program to not be able to communicate in some manner with the vsserv.exe executable. This executable is part of the Windows service called Bitdefender Virus Shield.

User's on Bitdefender's forums have reported installing a routine update, which then caused an error to appear that stated "Bitdefender Security Service has encountered a critical error!".

On reboot, Bitdefender would then show the following "Bitdefender services are not responding" message, which further indicated that it was problem communicating or connecting to the vsserv.exe executable.

How to fix the Bitdefender Security Service error
BleepingComputer has reached out to Bitdefender but at the time of this writing has not heard back yet. According to users in the Bitdefender forums, a fix has been pushed that supposedly resolves this issue.

If you are receiving either of the two errors above, you need to install a new update that has recently been pushed out by Bitdefender. To do this, right click on the Bitdefender icon on your desktop's system tray and then select the Update Now as shown below.

Updating Bitdefender
After the update is installed, the BitDefender icon should turn from grey to red (
). Once it turns red, reboot your computer. Some people have reported that if your icon does not turn red after installing the update, you should reboot anyway.

Once you reboot and login, your Bitdefender icon should now be red and your screen should look like the one below.

Bitdefender Working Again
This article will be updated when Bitdefender releases information on what had went wrong.

An update pushed by Malwarebytes today for their Malwarebytes Anti-Malware product has caused a lot of problems for those who use their program. This new protection update caused mbamservice.exe to consume a lot of memory and upwards to 90% of the computer's CPU. A new update has been pushed that resolves these issues.
Mbamservice.exe Using a lot of CPU
First reported in the Malwarebytes forums, numerous people have been complaining today about mbamservice.exe consuming large amount of memory and spiking the CPU at over 90% usage. This has caused some computers to crash or become too unstable to use.

In a post to their forums, Malwarebytes CEO Marcin Kleczynski explained that a bad protection update caused these problems and that a new update had just been released that fixes these problems.

Fixing Malwarebytes Anti-Malware
Fix the Malwarebytes issue can be tricky as when you reboot and login, mbamservice.exe quickly uses up a lot of memory and CPU. This can cause your computer to become unstable and unusable fairly quickly and prevent you from performing the update.

Therefore, I have outlined three different methods in order of preference that you can use to get the fixed update installed and MBAM working normally again.
