I use and have used for the past 3 years avg free version and it is very good and it does a complete virus scan of your computer from time to time and removes any unwanted trojans or viruses if you wish
I note I have something called ClamAV on my Mepis operating system not a clue how it works it says:-
antivirus scanner for Unix
Clam AntiVirus is an anti-virus toolkit for Unix. The main purpose of this
software is the integration with mail servers (attachment scanning). The
package provides a flexible and scalable multi-threaded daemon in the
clamav-daemon package, a commandline scanner in the clamav package, and a tool
for automatic updating via Internet through the clamav-freshclam package. The
programs are based on libclamav2, which you can use in your own software.
This package contains the command line interface. It has:
* built-in support for RAR (2.0), Zip, Gzip, Bzip2, Tar, MS OLE2, MS Cabinet
files, MS CHM (Compressed HTML), MS SZDD
* built-in support for mbox, Maildir and raw mail files
* built-in support for Portable Executable files compressed with UPX, FSG,
For scanning to work you'll need a virus database. You have 2 alternatives:
* clamav-freshclam: updates the database from Internet. This is
recommended if you have Internet access.
* clamav-data: for users without Internet access. Isn't updated at all
once it's installed. You can easily create your own updated package from
an Internet connected computer however, using clamav-getfiles.
It never seems to scan everything like the Microsoft ones do and not a clue how to test it. All loaded up with the synaptic package manager and about as clear as mud to me. Any info on what I should do with it would be great.
