Hi everyone. I am new here and this is my first topic and post. First I have AVG free installed in my PC. I wanted to test the resident shield and tried eicar.org. I tried to download eicar.com the first test for AVG resident shield, the first test went fine... AVG wouldn't let me download that file, then I tried downloading eicar_com.zip and I was able to download that file and AVG didn't seem to detect it. I downloaded to my desktop and scanned it with AVG. It detected one out of three files but couldn't quarantine. But that doesn't matter. What I am concerend is why did AVG Resident Shield allow me to download the zip test file?

Can anyone shed some light here please. Thanks in advance.

P.S: Maybe you guys can try it and maybe get an idea as to why this happened to me.

Zipped files are often used by the creators of malware because compressing the file(s) essentially "hides" them from anti-malware scanning (it is rather like putting a lovenote in an sealed envelope so the beloved's parents cannot read it). Hence the continual cautions from every security site and every E-mail provider (even with their OWN anti-malware scanning) to be very careful with any kind of zipped files.
Cheers,
John

So it means that zipped files cannot be detected by an anti-malware unless and until it's downloaded and scanned. Is it?

The zipped files, generally speaking, would have to be first extracted to your hard drive before any scanning would detect malware.

Hi sorry for the trouble taken to reply my post. Just one last question..... I know it's a stupid question but nevertheless I am asking.....

Do you mean even the Resident Shield would not be able to detect the virus stored in a zip file.

Sorry but I am that dumb. Thank you for the patience and your time.
