I downloaded Firefox 2.0 and tested the browser out. My computer gotten slower. This rootkit might’ve been connected with the Firefox. So I uninstalled the browser, and decided to stick to IE7, my current browser.

Any suggestions?

Could you temporarily disable avast, disable ‘Hide protected operating system files’ and enable ‘View Hidden Files and Folders’, and upload the above files to VirusTotal for analysis.

Should I send the file for analysis?

This snippet from the AT&T Bellsouth forum may help you a bit:

"Are you running AT&T Internet Security or have you run it in the past?

Avast has the virus in a vault so you are no longer threatened by it. What a vault does is apply attributes to the file so they can no longer be wrtten to ro read from by you system. The files are dead in a sence just taking up space on the harddrive.

The problem here may be that you are running 2 antivirus programs. Antivirus programs and firewalls both use rootkit technology to control and block viruses, manage programs. If you are running 2 antivirus programs … One may detect the rootkit technology of the other and mistakenly say its a virus since allot of the more advanced viruses use rootkit technology to mask themselves from the system. This is one of the things a good AV program looks for.

I guess what i am trying to say here is if you are running both Avast and AT&T’s programs. Avast may be picking up the rootkit technology in AT&T’s program and disabling it. Leaving the AT&T program worthless.

If you ran the AT&T program in the past. Avast may just be picking up leftover’s from the uninstall and in that case … no problem."

According to your post and your HijackThis log, you have it running.
“C:\Documents and Settings\Owner\Local Settings\Temp\Arc14.tmp[b]ATT_InternetSecurityWizardSetup.exe[/b]\Setup.exe{app}\ISWComHandler.exe”

“C:\Program Files\AT&T\Internet Security Wizard\ISW.exe”

Looks like a false positive. With avast! disabled again, put the file in a password-protected ZIP archive and send to virus[at]avast.com mentioning the password and the fact that the archive contains a possible false positive.

6

Do I have to include the password in the email?

7

Yes please. The only point of the password is to prevent email scanners from looking into the archive.

8

Thanks for sending file… False positive alert will be fixed in VPS 080528-0

Thank you. This antivirus really works. It helped me get rid of the MediaPipe Trojan “entry.dll” since I downloaded avast!. The other antivirus StopSign was a rip-off. I can’t believe they advertise a piece of crap. Reported StopSign to McAfee Site Advisor as a scam.
