Virus not detected by mail scanner

Avast Free Antivirus / Premium Security
1

I received a zip file wich was said not infected by avast mailscanner, i unzipped the file and scanned it with the right click avast scanner in the explore ( not infected) and only when i clicked on the .exe file, the standard shield beeped and recognised a trojan. I clicked on erase file and my system (win98se) freezed… the trojan was installed and remained in memory… :-\

only a full system scan removed it…

Can i send you (where?) the infected file in order to improve the mail scanner ?

I guess u didn’t enabled the Packers scan.well packers is basically ment for scanning for compressed files like .zip,.rar. and .raj e.t.c.To enable this option pls goto start avast anit-virus scan and goto simple user interface and goto tasks folder and Right click on resident protection,it will give a warning just click OK and goto internet mail,on internet mail check for packers and tick ALL PACKERS.That’s it.If it all it did not scan the compressed files do right click manually and scan with avast.It does fails to scan when the compressed file is password protected.Which all anit-vius can’t do that kind of file.

all packer were ticked :frowning: :frowning: :frowning:

So, if you scan the ZIP file (without unpacking it first) with the rightclick scanner (or e.g. Simple User Interface), is the virus detected?

great it it’s detected since new update 0509-1 (Win32:Beagle-BA [Wrm]) !!! ;D

unfortunately, the update arrived a bit late…

The scanner also deleted the “wiwshost.exe” file in the c:\windows folder am i clean nows? ???

6

What did you do with the infected file? I suggest to let avast! delete the file (maybe use a boot-time scan).

7

i kept the zip file (if avast wants it…) and deleted the registry enters and avast deleted the wiwshost.exe file

something “funny” with that virus is that it prevented zonealarm to start at next boot (very smart!!!) and i had to reconfigure my zonealarm as if it was the fistr time i launched it… :cry:

8

:frowning: >:( >:( in fact the virus erased all the informations of installation : my add/remove software zone is empty in the windows system panel :‘( :’( :cry:

how can i restore it ? (i guess i can’t)… :‘( :’(

9

can i reinstall avast without losing all my personalized settings (to have it again in the windows desintaller ?)

10

I have often wondered what people do to get infected.

11

Oh…icc it was the lastest virus…that why it was late for it to deduct that virus…good now that Avast had updated to their virus definition. ;D

12

ok i’ve been playing with fire :stuck_out_tongue: :-[ but it was scientific curiosity (“why did avast say file ok?”) … and curiosity killed the cat !

13

If you are going to open things out of scientific curiosity, I suggest you get your backup/recovery strategy in place first. By far the easiest is to do regular image backups of your HDD and daily backups of your data files, etc.

14

can u tell me if i can reinstall avast without loosing my settings ???

15

Save your avast4.ini file is as far as you can go I think (not certain), it should save a good deal of your settings. I don’t know if there might be other data files that might be worth saving.

Besides the avast4.ini file you can save avast4.mdb (from data folder) and DefTasks.xml (from main folder). :wink:
