Dear Avast member,

Could you revise the Viruse Definition: 110816-1 ?

Since, it caused fail to open all PDF files. As it shows Malware-gen........

Thanks !!!

As you seem to be the only one with this problem you will need to provide alot more information as to what was detected and what pdf reader your using and what avast shield blocked this ?

I'm using PDF-XChange Viewer as pdf reader.

And all pdf file type cannnot be opened. And it is not only happened in 1 PC, other PCs which are using Avast Pro 4.8 with this false position problem.

I need to turn off Avast protection function and make opening the PDF files correctly.

As the same time, I tested it with Avast Pro 6.0 and using same virus definition. It seems no problem for opening Pdf files.

So, I think it is just caused the problem in using ver 4.8

The problem is happened in Win XP SP2 / SP3

And, I have not take a look for PC which using WinMe. But I guess there are same happen.

The reason why I do not update to Avast Pro 6.0 because I still have several PCs with WinME.

Thanks

Does it possible to keep the current state ?

I means other than update to 6.1.

Since, there was no problem the day before. And, the program update will cause the heavy effort to me.

Thanks !

1. Does it possible to keeps the current state ?
2. I means other than update to 6.1.
3. Since, the was no problem the day before. And, the program update will cause the heavy effort to me.

1. Sure, until 4.8 is finally dropped, which will happen sooner than later.
2. There is no 6.1... ;)
3. I guess you're talking about a signature update, as there was no program update for 4.8 for a long time.

There are not many 4.8 users left, as also the business products got updated lately.
And as you're the only one who reported any problems....
Well, wait for the next VPS update and see, if it works for you.
