I am running Windows XP SP3, with IE7.

About 6 days ago, I noticed that, intermittently, when I clicked on a link within a search engine, I would be redirected to a totally irrelevant website (usually running some promotion). Overall, the system was running probably 30-40% slower by my estimation.

I immediately ran Windows Update, but there were no outstanding patches etc. I then updated my A/V (Symantec A/V 10.0 Corporate), did the same with Spybot 6.2 as well as Defender. I ran full scans with these, but nothing was reported.

I then proceeded to run Sophos Anti-Rootkit, but again, nothing was reported. Despite this, I kept going. I looked up "google redirect virus", and decided to investigate some relevant registry keys. However, when I tried to run Regedit from the Run menu, the desktop seemed to stall momentarily, before recovering, but there was no sign of Regedit.

At this point, I went to Kaspersky's website and ran their online scanner. Again, nothing reported. The same thing happened after running McAfee's online scanner.

Other programs I tried were Malwarebyte's scanner, as well as Gmer, Rootkit Hook Analyzer, RUBotted and McAfee's Rootkit Detective - nothing reported. Note that I had to rename Gmer, otherwise it would not run at all.

I then uninstalled Symantec's A/V and installed TrendMicro's PCCillin and ran a full scan. It managed to report some changes to the LMHosts file, and removed the offending entries. However, the same behaviour continued.

I even booted up the PC using Bitdefender's Rescue CD (Linux-based live CD, running latest definitions), but it found nothing as well.

I would really appreciate your help here. The DDS file is attached.

Many Thanks

Welcome to the BleepingComputer Forums.

Since it has been a few days since you scanned your computer with HijackThis, we will need a new HijackThis log. Please download Trend Micro - HijackThis. Do a new scan with Trend Micro - HijackThis and post it in your next reply.] Thank you for your patience.

Please see Preparation Guide for use before posting about your potential Malware problem.

If you have already posted this log at another forum or if you decide to seek help at another forum, please let us know. There is a shortage of helpers and taking the time of two volunteer helpers means that someone else may not be helped.

Please post your HijackThis log as a reply to this thread and not as an attachment. I am always leery of opening attachments so I always request that HijackThis logs are to be posted as a reply to the thread. I do not think that you are attaching anything scary but others may do so.

While we are working on your HijackThis log, please:
  • Reply to this thread; do not start another!
  • Do not make any changes on your computer during the cleaning process or download/add programs on your computer unless instructed to do so.
  • Do not run any other tool until instructed to do so!
  • Let me know if any of the links do not work or if any of the tools do not work.
  • Tell me about problems or symptoms that occur during the fix.
  • Do not run any other programs or open any other windows while doing a fix.
  • Ask any questions that you have regarding the fix(es), the infection(s), the performance of your computer, etc.
Thanks.
