but strange things happening

You need to be more specific about what strange things are going on as not all issues with your computer are malware related.

Hi,

Thank you for your reply.

The things that happen are webpages don't come up or sometimes get redirected.

Didn't want to post a HJ log until we go through the processes in addressing this issue.

Can post the log file from SuperAntispyware & Malwarebytes if you like.

Cheers,

Your Malwarebytes Anti-Malware log indicates you are using an outdated database version.
The database shows 3798. Last I checked it was 3825.

Please update it through the program's interface (preferable method) or manually download the definition updates and just double-click on mbam-rules.exe to install. Then perform a new Quick Scan in normal mode and check all items found for removal. Don't forgot to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

Note: You should always update database definitions before performing a scan...that includes SUPERAntispyware.

Please perform a scan with Kaspersky Online Virus Scanner.
-- Requires free Java Runtime Environment (JRE) to be installed before scanning for malware as ActiveX is no longer being used.
-- This scan will not remove any detected file threats but it will show where they are located so they can be cleaned with other tools.
  • Vista users: need to right-click either the IE or FF Start Menu or Quick Launch Bar icons and select Run As Administrator) from the context menu.
  • Read the "Advantages - Requirements and Limitations" then press the Posted Image... button.
  • You will be prompted to install an application from Kaspersky. Click the Run button. It will start downloading and installing the scanner and virus definitions.
  • When the downloads have finished, you should see 'Database is updated. Ready to scan'. Click on the Posted Image... button.
  • Make sure these boxes are checked. By default, they should be. If not, please check them and click on the Posted Image... button afterwards:
    • Detect malicious programs of the following categories:
      Viruses, Worms, Trojan Horses, Rootkits
      Spyware, Adware, Dialers and other potentially dangerous programs
    • Scan compound files (doesn't apply to the File scan area):
      Archives
      Mail databases
  • Click on My Computer under the Scan section. OK any warnings from your protection programs.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
  • Once the scan is complete (the 'status' will show complete), click on View Scan Report and any infected objects will be shown.
  • Click on Save Report As... and change the Files of type to Text file (.txt)
  • Name the file KAVScan_ddmmyy (day, month, year) before clicking on the Save button and save it to your Desktop.
  • Copy and paste (Ctrl+C) the saved scan results from that file in your next reply.
-- Note: Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

Your log shows that the Outlook.pst file is infected.

Outlook.pst is a hidden (by default) data file that stores calendar, contacts, email messages and other items for your mailbox. This file is located in the C:\Documents and Settings\<user>\Local Settings\Application Data\Microsoft\Outlook folder but it can be moved to any location on your computer. Over time the Outlook.pst file can become corrupted, damaged or show signs of malware infection (usually related to email attachments). When that occurs, you need to delete the email attachments without opening up the attachment itself. Afterwards, compact the .pst files by clicking Properties > Advanced > Compact File. Another option is to just create a new Outlook profile which creates an empty PST automatically and remove the old one. If you don't know how to delete, compact or create a new PST profile, please refer to Maintaining Outlook's PST Data File.

BTW where do we attach image for the post if we need to.

How to take and share a screen shot in Windows

You can upload it to an image site such as Photobucket, Media Fire, TinyPic or ImageShack and provide a link to the url address back here.

The redirecting with long urls may be related to Google's use of scripting when conducting a searches so try is stopping active scripting. Open Internet Explorer and go to Tools > Internet Options > Security > Local Intranet > and click on Sites. In the next window that opens, click Advanced under Add this website to the zone, Add: www.google.com and click Close.

Next click the Custom level ... button in Local Intranet, scroll down and disable "Active scripting" which should ensure none of Googles scripting runs when you search.

At this point I can't tell if the redirects are related to malware or Google scripting so that's why I asked you to disable it. If the redirects are happening in Firefox, then further investigation should be done. Many of the tools we use in this forum are not capable of detecting all malware variants so more advanced tools are needed to investigate. Before that can be done you will need you to create and post a DDS/HijackThis log.

Please read the pinned topic titled "Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help". If you cannot complete a step, then skip it and continue with the next. In Step 7 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

When you have done that, post your log in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the Malware Response Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the Malware Response Team.

Please be patient. It may take a while to get a response because the Malware Response Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have posted your log and are waiting, please DO NOT "bump" your post or make another reply until it has been responded to by a member of the Malware Response Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another Malware Response Team member is already assisting you and not open the thread to respond.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/301035/webpage-tries-to-redirect-malware/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
