To dj Mcrae.
Obviously a little clarification needed.
No antivirus is 100% bulletproof. Nor any other kind of security protocol, although there are some (not single products, by the way, but layered applications and user- procedures) that can come very close to it. A combination of imaging software, sandboxing, and behaviour blockers, combined with a good two way firewall is pretty bulletproof.
I say "pretty bulletproof" because there are constantly new types of threats under development. (As an example, researchers have been able to create malware which cloaks itself in the hardware of a PC, so far undetectable.)
These "pretty bulletproof" applications are not mainstream, nor for the average user. Not yet, anyway. The "average user" is usually quite happy, for a while, with whatever the vendor pre-installed on the computer when purchased. Millions of other users choose a different, sometimes freeware solution, which typically involves an antivirus, a demand antispyware scanner or two, and maybe a two way firewall, for better outbound protection than the one built into the OS.
The "big three" free AV's I refer to are Avast, Avira, and AVG. A fourth contender is PCTools AV, a bit of a new kid.
And I believe you are doing users a fairly large disservice by making claims against one of these tools which appear to have no validity. They all score well in independent testing, some score better than some big-name paid AV/security solutions.
The "average user" on these forums might well be a little more technically inclined than average, because the nature of our employment lends itself to that. And it only takes a quick look through this forum to see that some are extremely knowledgeable about PCs. I don't include myself in that group, and have never pretended to. I do know a little about security applications, and what is likely to keep the "average user" safe, or not. And, although I personally don't use AVG I believe it, especially as part of a security strategy, is at least close to being as good as a lot of the other AV's available.
I have no idea how good the current version of AVG is at trojan removal, I use different software for that if it's ever needed. (So far, for over a year, it has not been needed.) But the apparent contradictory comment-concerning AVG AV7.5- is valid. If an AV can prevent a trojan installing, which most do, via detection, its payload can't install nor "phone home". If you are unfortunate enough to have one install anyway (eg a new variant Vundo or Smitfraud), more specialist tools are required. It is quite possible that AVG 8 may be better at this, due to the included AS. I don't know.
Nor, I strongly suspect, do you.
I was originally going to finish my earlier post with the comment "put up or shut up", but changed it to "perhaps you better explain what you mean", because it sounded less provocative.
Really, if you are going to make unfounded allegations of a scaremongering nature, your credibility suffers without an explanation. No "goating" was intended.
So. Put up or shut up.
