Avast free edition let me down when it comes to trojan detection

Does the free version of Avast have optimized trojan scanning? Because I have a file with several trojans contained inside which Avast did not pick up.

How do I know? I scanned the same file with NOD32, which found it. The same with McAfee antivirus. The company I work for has McAfee on all the workstations, and I scanned it there, too(and the McAfee virus definitions were three months out of date at the time of the scanning). AVG picked it up, too, but after the file infected a friend’s PC. NOD32 called it “a variant of the Win32/Tool.TPE.A app,” Mcafee called it “Tool-TPatch,” and AVG called it “Trojan horse generic2.ATS.”

Do I need to upgrade to the pay version of Avast to get the extra protection? Because at this point, if I’m going to spend any money, I’m going to spend it on NOD32. It’s way easier on resources.

By the way, this is Avast 4.7 I’m talking about, and it’s on a Windows XP SP 2, fully patched machine.

Judging from a name it’s not really a virus/trojan/worm but some sort of tool. And most of such tools are basically just riskware, not really viral…

What is the infected file name, where was it found e.g. (C:\windows\system32\infected-file-name.xxx) ?

Judging by the name it could be as RejZoR said a tool which could have a legitimate purpose on your system, you could have installed it or it is part of a program you installed. The file name and location could help you determine that and if it is legitimate.

This is a program created with a toolkit. The purpose is to modify files of an application on the computer in order to change the functionality of that application in some way.

You could also send a sample to avast, zip and password protect it and send it to virus @ avast.com without the spaces and put the password in the body of the email, give a little info about it, what version of avast, 4.7.892 and what VPS version you are using and possibly a link to this topic.

Edit, interesting what Kasperspy (viruslist.com) turn up on this.

Well, I don’t feel so bad anymore. Hey, thanks for the replies. Sorry I dogged out Avast.

It’s build 4.7.892, by the way.
