Time for some meat with the potatoes:
- Perhaps the reason why AVG has gotten slower is that it is scanning
more thoroughly! That's exactly what you want an antivirus program to
do. Some virus writers use devilishly-clever routines in order to
subvert antivirus programs. The AV software must, in turn, respond with
equivalent craftiness. This is no simple matter. I want to know that the
AV program is working really hard!
So, what do you mean by "better?"
Or, to put it another way, "Do you want your chicken cooked fast or do
you want it cooked enough?"
What I've learned from hard experience is that I need four things from
an antivirus provider:
The first is for the program to nab the invader, isolate it, and put it
to death. I think that most programs do this part OK.
The second is for the program to reverse any damage that the invader has
caused to files on my system. Those files may be data, executable code,
or both. It may also consist of renaming files. How well does your
program do this?
The third is for the program to remove any software that may have been
placed on the hard drive by the invader. Last time around, it was me who
found the invader's second program. My antivirus sure didn't.
The fourth is for the publisher to provide some method for reversing any
changes that the invader has made to my registry. This typically is not
an automated procedure, but is a set of instructions to be carried out
by the user to manually edit the registry.
**** Note that the virus's damage has not been undone until this last
step has been performed.
My experience with various antivirus software is that many programs fall
down on the third and fourth of these. I'm glad to see these two
companies doing antivirus work in the Czech Republic.
I tried Avast last year and abandoned it -- it felt too much like a
lightweight to me. I experienced another problem, too, which I've forgotten.
With the double worm infection that I had to eradicate last week, the
only company that I found that addressed my registry problem was Norton
Antivirus, and even that was not for the particular version I was
afflicted with. For this reason, I will probably be abandoning both of
these Czech products and will pay for Norton.
Note that I have no love for Symantec, the publisher of Norton
Antivirus. I am disgusted by the way that they relate with their
customers and avoid personal support. I was also infuriated by the
performance (or lack of it) of two versions of their Norton Systemworks
on two different computers and two operating systems.
So, so far, in my own life, it appears that Norton Antivirus is the only
game in town. If you've found another outfit that can provide an
affordable, total virus removal that really works, please, for godsake,
let me/us know!
Unfortunately, there are some things that freeware has not been so good
at, things that are too important to treat lightly.
