I have been disappointed with AVG ever since they made a decision in April 2010 to partner with LimeWire
and promote the use of peer-to-peer (P2P) file sharing
, a security risk which can make your system susceptible to a smörgåsbord of malware infections
, remote attacks, and exposure of personal information.
With the release of AVG 2011, there have been numerous complaints about issues and conflicts with other security tools like Malwarebytes' Anti-Malware. Read the related discussions at AVG:
There have been reports of issues with the computer starting properly on 64-bit Windows sytems
for which AVG has had to release these fix instructions
There have also been reported problems with computers after using
new features like PC Analyzer
and PC Tuneup
which purport to fix registry errors in order to make the system more stable and various optimizing tools which can make changes to system settings.I do not recommend the routine use of registry cleaners/optimizers
as they are extremely powerful applications that can damage the Windows registry
by using aggressive cleaning routines and cause your computer to become unbootable. The registry is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component
because it is where Windows "remembers
" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable
. Using registry cleaning tools unnecessarily
could lead to disastrous effects on your operating system such as preventing it from booting properly. For routine use, the benefits to your computer are negligible while the potential risks
For these reasons, I no longer recommend AVG as a free alternative.
If after using PC Tuneup
, you experience issues with some programs, be aware that most registry cleaners and optimizers will prompt you to back up the registry
BEFORE using them. These backups are usually saved in the program's folder so they can be accessed and used to restore the system in the event you encounter issues after running the registry cleaner. If that is the case, you can open the registry cleaning program which made the changes and look for an 'undo
' feature which allows you to restore the registry backup.
If no backup was made, you can also try using System Restore
or System Restore from a command prompt in Safe Mode
. If that does not resolve the problem, then you probably will need to reinstall those programs which were affected and no longer working properly.
