AVG update offered repeatedly

Several AVG users reported the same LinkScanner update is being offered repeatedly, even though it appears to be successfully installed. Should you face similar situation, please proceed as indicated in this forum post.
Feel free to contact AVG technical support should you require further assistance.



Anti-Virus inactive?

AVG Forums visitors sometimes report AVG Anti-Virus component is inactive. This issue is usually caused by hardware failure. We recommend running memory and hard drive tests to check your hardware health should you face similar situation. If the tests reveal that any of the RAM modules or hard drives is faulty, please consult local computer repair shop or your computer vendor for further guidance. The respective faulty component will need to be replaced.
If the hardware appears to be perfectly healthy and the issue persists, please contact AVG technical support or describe the issue in AVG Forums to allow us investigate the issue.



System slowed down?

After installing an in-background-running software, like the antivirus, the system is to be expected to slow down as more system resources are being used continuously. While the slowdown is not apparent on new computers, it may be noticeable on slightly older systems. We strongly recommend checking hardware requirements before installing similar software. AVG 2012 Free Edition minimal and recommended system configuration can be found in this forum post.
Also, please note that running more resident security applications often slows the system down. It is recommended to use only one resident (on-access) security software. If you would like to install additional software, make sure to install only the on-demand components. Having more resident security modules running may even cause trouble when removing a detected infection, at the end of the day.
In case you would like AVG technical support agents to investigate a slowdown issue noticed after AVG installation, please do not hesitate contacting AVG technical support or describe the situation in AVG Forums.



AVG LiveKive login issues on mobile devices

A few users reported they are not able to log into the LiveKive client on their mobile devices even though the correct credentials were provided. We have induced the issue in our environment with different mobile devices as well. Here you can see an example of the error message displayed on IOS devices.
The issue is being investigated by developers at the time of writing this short article. Please accept our apology for the inconvenience.



Rootkits

In the past week, we noticed several users fighting rootkits. Please note that although AVG detects rootkit-like behavior, some of the detected rootkits could be used by legitimate applications and does not mean any harm. Before removing a rootkit, make sure it is not used by a legitimate software. If unsure, please contact AVG technical support for assistance.
Please check these FAQ articles in case you would like to know more about rootkits and their removal:
What is rootkit?
How to deal with rootkits?
Modern rootkits overwriting the Master Boot Record (MBR) may sometimes prevent the MBR sector from being fixed when the operating system is running (and the rootkit itself is active). In such case, the MBR needs to be overwritten with the host operating system offline. This can be done by the Windows recovery console.
Rewriting the MBR improperly may prevent the operating system from booting. We recommend performing this operation only if you are absolutely sure or if asked to do so by AVG technical support (detailed information will be provided in such case). More information about rewriting the MBR sector can be found in this AVG Forums article. After fixing the MBR sector, we strongly recommend running a full computer scan using updated AVG to remove possible infection remnants.
Please do not hesitate contacting AVG technical support or describe the situation in AVG Forums if an infection cannot be removed or is repeatedly coming back after its removal.
