when i open up 'my computer' or windows explorer to browse, the window and all task bar items disappear after about 10 seconds or so. nothing else is affected.
I think this is caused by some sort of virus on my computer.
ive tried a full system scan with kaspersky - nothing
tried spyware /adware scans - nothing
tried vundofix - no files detected

ive got a log from hijackthis - anyone able to help??

I have moved your Topic that includes a HijackThis log here to the Misplaced HJT Logs forum. You posted your log in a forum not intended for HijackThis logs analysis and probably missed the directions we provide to those who require assistance. We can only allow topics with such logs in the HijackThis Logs and Malware Removal forum. This restriction is to ensure you get the best help available, from those who specialize in malware anlaysis and removal. It also should prevent you from receiving ineffective or even potentially dangerous advice, whether well meaning or not.

Prior to posting a HJT log, we ask that you please read and follow all instructions in the pinned topic titled Preparation Guide For Use Before Posting A Hijackthis Log. Following the steps in this Guide will allow the HJT Team to quickly help you with specific fixes for what may remain on your system.

Please complete all the steps in the Guide. If you have performed some of them already, then just continue with the next. There are instructions for downloading and running Deckard's System Scanner (DSS) which will create a hijackthis log for you, or automatically download and install the most current version of HijackThis if it's not already installed on your computer.

Please note that it is important that Deckard's System Scanner be run and a log created while in normal mode. If you run it and create your log while in safe mode, you will be asked to redo it again properly. When you have completed those steps, start a new topic in the HijackThis Logs and Malware Removal forum as directed in the Guide to post a new log.

Please DO NOT post any more logs to this topic, or post a log again in the wrong forum.

The Misplaced HJT Logs forum is strictly a holding area where the BC Staff can assist you with preparations for and to properly post your log. If you have a question or encounter a problem in the Prep Guide, please do post back to this topic; that is what it is here for.

When your new HJT log is posted in the proper forum, please reply to this topic with a link to your new topic. Once that is done, a Member of the HJT Team will analyze your log and assist you with step by step instructions to clean your computer or otherwise advise what needs to be done.

Thanks for your cooperation and good luck.
The BC Staff
