  1. My computer has been infected with the Trojan.Brisv.A!inf trojan for some months now and I still havent been able to remove it. I've tried Symnatecs removal tool, but its been no help. I've scanned my PC with Malwarebytes Anti Malware, SuperAntiSpyware Pro, CCleaner and the like, with no results.

    Your help would be greatly appreaciated in removing this nuisance.

    A note: to the information kritius left for you: you have indicated that you have scanned with both Malwarebytes and SuperAntispyware, but you have not provided a logs for either. You will need to UPDATE each of these programs and run new scans. Then attack those two logs on your next post.

    Download and run HijackThis AFTER you have scanned with the other two programs and also include that log.

    There are additional steps in the link kritius left for you. It's best you follow all of those steps. Some malware requires special cleaning programs but unless we see the logs, we cannot make that determination.

    I would like you to do an online scan so that we can what else may be in your system,

    Run Kaspersky online scanner

    With the exception of Internet Explorer, which must be used for this scan, keep ALL programs closed

    Note: It is recommended to disable onboard antivirus program and antispyware programs while performing scans to speed up scan time and to make sure there are no conflicts.

    Do not go surfing while your resident protection is disabled!

    Once the scan is finished remember to re-enable resident antivirus protection along with whatever antispyware application you use.

    Do an online scan with Kaspersky Online Scanner in Internet Explorer. You will be prompted to install and run an ActiveX component from Kaspersky, Click Yes.

    Note for Internet Explorer 7 users: If at any time you have trouble with the accept button of the licence, click on the Zoom tool located at the right bottom of the IE window and set the zoom to 75%. Once the licence accepted, reset to 100%.

    • The program will launch and then start to download the latest definition files.
    • Once the scanner is installed and the definitions downloaded, click Next.
    • Now click on Scan Settings
    • In the scan settings make sure that the following are selected:

      o Scan using the following Anti-Virus database:

      o Extended (If available, otherwise use standard)

      o Scan Options:

      o Scan Archives

      o Scan Mail Bases
    • Click OK
    • Under select a target to scan, select My Computer
    • The scan will take a while so be patient and let it run.
    • Please do not use your computer while the scan is running. Once the scan is complete it will display if your system has been infected.
    • Click the Save Report As... button (see red arrow below)


    • In the Save as... prompt, select Desktop
    • In the File name box, name the file
    • In the Save as type prompt, select Text file (see below)


    • Include the report in your next post.

    I tried the Kaspersky Online Scanner but it keeps telling me 'You need to install Java version 1.6 or later to run Kaspersky Online Scanner 7.0' even though I have Java 6 Update 12 installed. So thus far i cannot perform a scan.

    You are saying this doesn't work?

    Thanks for all those who contributed to my thread.

    I re ran the symnatec removal tool in safe mode and this time it did the trick. So once again, thanks to the senior members at techspot for their assistance.

    Is there anything you recommend I do to safe guard my pc from these type of infections in the future?

    I thought that you might not have used Safe Mode. Glad that worked for you.

    Yes, keep in mind that YOU are the first line of security for your computer! Where you go, what you do, how you handle mails and attachments, where you leave your email address. So, if you'll forgive me, I'm going to put your user name to 'use:

    BWise is which site you surf to.
    BWise and don't click on pop-ups.
    BWise and don't open email from someone you don't know.
    BWise and don't open attachments EVEN if they are from someone you know unless you know they are coming and what the content is.
    BWise and never leave your personal email address on the internet.
    BWise and install one good antivirus program, one firewall and at least 2 spyware/adware programs. Update and scan with them regularly.
    BWise and stay away from file sharing programs and sites.
    BWise and be careful of what you down;oad and the site you download from.
    BWise and only have those processes starting on boot that you need: the antivirus, firewall (if you have 3rd. party firewall, touchpad for laptop, possible network process.
    BWise and do regular maintenance on the system: disc cleanups, error check, defrag, uninstall any program you aren't using.

    If you are really this 'wise', you should have safe and enjoyable computing!
