possible trojan horse?

Yup, i can attest to this also.

I ALWAYS trust any anti-virus processing to be reliable enough to warn me about corrupted files. What if they are wrong? I only lose the wanted tiny file. What if they're right and i don't react as suggested? I'd be stuck with the stupid Trojan and would have to endure its presence for months on end without my better knowledge.

The lesson to learn about any AV programs is that they are WORKING for the users and are intended to protect a PC from malwares in all shapes and origins.

I'd even go as far as to say... all downloaded content(s) MUST be monitored, even if one kinda trust the sources. Sometimes, even root-kits can blast a drive or handover control of sensitive areas of the OS to hackers (of the very BAD kind).

Into the Vault. Delete. Goodbye trojan horse(s) and alikes.

I'll no-glare the corresponding dx file all by myself if i really want to, thank yo very much.

It's a known false positive with WinRAR's self-extrator, and an old one at that. I'm actually pretty surprised that AVG hasn't fixed it by now. Simplest thing to do in any case if you're concerned is just open it through a zip/rar program rather than using the SFX directly.

And also report the false positive to AVG tech support.

You can also add your false positive file to the ignore list in AVG. Opening the file with WinRAR or WinZIP should not work either. AVG should prevent you to open any file with a virus anyway (you will see "access denied" message). The reason is viruses spread via Word, Excel, Outlook, VB... too. It is several years since I do not work for Grisoft anymore, but I think those things should not have changed.

And one more thing: you can ask for their support only if you are a registered user.
