Hi ORGUMN, and welcome to the forum.

There is no such "problem" currently.

Can you please be more specific.

a-squared does not flag C:\windows\explorer.exe

As for HiJackFree you may mix the real detection and the yellow/red faced indications, which are just the notifications that "it could be" or was indeed flagged in the past as being infected.

Be very careful with this Tool - it is for experienced users only!

So, do not make the decisions based on what you are seeing unless you are sure and have such experience.

You may run on-line full scan;

provide the link to the result and ask the certified malware removal specialist to review the log file

What you showed is just a report of Processes List

Here is an extract from my report and the Explorer.exe

...652	C:\WINDOWS\Explorer.EXE		6.00.2900.5512	Microsoft Corporation
3744	C:\Program Files\Mozilla Firefox\firefox.exe		1.9.1.5	Mozilla Corporation...

Why you are concluding that it's infected based on what you posted?

It would be nice if you've saved a-squared scan report with "Trojan.Win32.Patched.aa!A2" detection

My regards

P.S. Please do not use Inline posting of reports (your report is incomplete anyway)

Attach log file(s) or the link as it was suggested above

Read Forum Posting Rules and provide information about the system as in #2)

HI,

There is this problem with various individuous in the internet.

The a-squared free show me this infection !!! but, i do not know to save the log of the a-squared free software then, i only posted: " a-squared free detected Trojan.Win32.Patched.aa!A2 in C\windows\explorer.exe " and the log of the a-squared HiJackFree for helpful.

Anothers detection softwares do not detect this malware in my system. The same occur with others friends here in Brazil.

Here in Brazil, everybody think that is a false positive but, i want to have conviction with you of the EMSI software.

I will to try a on-line scan, Thanks.

Hi ORGUMN, and thanks for reply.

I hope you understand that from what you posted & from my example - no conclusion can be made that Explorer was flagged

Sure please try on-line scan and saving that report bit be careful and do not make "fast decisions" as it was suggested above.

As for

...The a-squared free show me this infection !!! but, i do not know to save the log of the a-squared free...

Please see the attached image.

That is the button you have to use after the scan finished and then please save and attach the report here

Regarding the HiJackFree as in your initial request other 2 attached images are those "Yellow & Red Faces" I was talking about

My regards

Hi ORGUMN,

Please follow the posting rules and attach the report instead of in-line posting.

Provide the info about the system as it was asked in the 1st reply.

The Deep Scan of just 347 files that lasts only 3 minutes(!?)

... that is something I've never seen yet :unsure:

Anyway the update of a-square was done

Last update: 5/12/2009 19:07:54
but the scan was run on
11/12/2009

In addition the report was edited Please don't do that...

The Software has to be updated ... but irrespectively despite some questions about the report - submit the flagged Explorer to EMSI developers from the detection list for analysis - that is the only way to find the truth

My regards

I have the same problem.

A-square reports only:

[1764] C:\WINDOWS\Explorer.EXE In Quarantaine Trojan.Win32.Patched.aa!A2

In Quarantaine

Bestanden: 0

Sporen: 0

Cookies: 0

Removing this infection is reported to be impossible.

Checks with other scanners (Ad-Aware, Malwarebyte's Anti-Malware, Spybot) do not report this infection.

I am using Wi XP prof servicepack 3, Eset NOD32 antivirus and a firewall.

Regards,

Corneille

Hi corneille, welcome to the forum

1) a-squared does not flag Explorer here.

Are you scanning with the latest updated signatures?

2) Irrespectively please submit the file to EMSI developers for analysis

3) be very careful and don't attempt to quarantine such vital system file even if it was compromised by malware. Read this Sticky

4) if you received a message from a2 about inability to quarantine/delete and or your system is misbehaving
