AVG Technologies CZ, s.r.o. Files

The following are the AVG Technologies CZ, s.r.o. files I've gathered, thanks to the FreeFixer users.

The FreeFixer tool treats files from AVG Technologies CZ, s.r.o. as safe, which means that the AVG Technologies CZ, s.r.o. files will appear with a green background and that there is no removal checkbox for the file. However, as you can see in the scan results below, a few of the anti-virus scanners detects the AVG Technologies CZ, s.r.o. file(s).
