Avast Free Antivirus / Premium Security
1

Hi

i installed on a pc avast 6 last built ,windows 7 32bit
but is the shield buggy , i’m talking about persistent cache

well i installed avast and i did perform a full system scan , with "store data scanned files in persistent cache " it’s enabled

and in the shield i have use trasient and persistent caching

well
every time i run photoshop for example , the shield scans it and all the dll

i remember avast 5 skipped , because they were in the persistent chache

is there a bug?

thanks

Welcome back mantra… A long time I did not see you round :slight_smile:
Well, there shouldn’t be a bug in the persistent/transient cache.
Sometimes, after the full scanning, maybe just booting.

thanks man , but i did , i run a full scan , reboot

but the resident shield still scans every files like .exe ,.dll and so on

may you test it ?
in the resident shield log option you can set all so avast shield will report every file cheched(not only virus)
to me the resident shield scan such files everytime

did not find avast6 more fast thne avast5 , on the contrary

Did you change the File Shield settings?

Use transient caching - if transient caching is used, a file that has been scanned, and in which no infection was detected, will not be scanned again the next time it is accessed. However, this is only valid until the next virus definitions update, as the file may contain an infection that was not previously detected but which may be detected based on the new virus definitions. Also, information that the file is clean will only be stored in the computer's operating (temporary) memory. This means that when the system is restarted the information will be lost, therefore the file will also be scanned again the next time it is accessed after a system restart. This box is checked by default; if you want files to be scanned every time they are accessed, this box should be unchecked.

Use persistent caching - if persistent caching is used and a file is verified as clean, this information will be stored in the permanent memory. This means it will not be lost after a system restart and it is also not affected by virus definition updates. Verified clean files are files which are guaranteed not to contain any virus infection e.g. some operating system files, files signed by trusted publishers, or other files covered by the avast! whitelist. This box is checked by default; if you want all files to be scanned regardless of their trust status, this box should be unchecked.

Photoshop like all Adobe products has a history of containing Malware.

Under “Sensitivity” if you have heuristics set to high and all the boxes checked you will get pretty thorough scan of all the files.

I don’t know how to troubleshoot…
If a programmer can help here you can solve it, and I can learn from it :slight_smile:

men can do a short test

run some program that you are sure you have in the persistent cache
and check if avast 6 scanned these files?

thanks

Sensitivity at default should be “normal”

Which radio buttons under Sensitivity are checked?

Photoshop may be legit but that doesn’t mean that it doesn’t have malware and exploit related problems. Adobe products have a bad history of effective malware and exploit attacks.

Did you scan the Photoshop directory chain with Malwarebytes?

They do not seem to be scanned… Where are you checking (and what are the settings to achieve the log)?

12

in the shield settings , i set to log every file , errors ,virus and so on
so i can understand which files does the shield scan

i have the free version

13

Sorry the stupid question…
Which is the log file name and path?

14

man you are using avast by years :frowning:

i don’t know which os are you using , w7 programdata-> avast → report ->shield
are you using xp ?
by the way you can do a search for the log

can you add a screenshot about avast shield report log setting ?

thanks mate

mantra… I really cannot find anything in log…
In the report folder I’ve found the log called usntr.log
I’ve taken Winword as an example:

30/04/2011 12:13:17 Processing file C:\Program Files\Microsoft Office\Office12\WINWORD.EXE…
30/04/2011 12:53:47 Processing file C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Microsoft Office\Microsoft Office Word 2007.lnk…

I think 30/04 was the last time I’ve booted the computer. So, seems that for me the cache is working.
