Trojan moved to chest, but CPU usage still at 100%

Hi,

Over the last couple of days my computer has been getting noticebly slower, to the point where I can’t watch avi films without them freezing, and cant run photoshop with media player running etc.

I noticed lots of processes running in task manager that I didn’t recognise so ran a boot time scan, which came up with… “Threat: Win32:FakeAlertOR-[Trj]” - so I duly selected move to chest and finished the scan (which incidently took a lot longer than it used to)

After the scan I finished booting my PC and checked task manager - which was still runnign at between 80-100% CPU usage. It has in fact dropped to a normal looking level now, but as soon as I try and run VLC media player again it jumps right back to 100%.

I’ve includede a Hijackthis log and a screen shot of the task manager from when I first turned my PC on earlier.

Any help much appreciated,

Ollie

Try this

Malwarebytes Anti-Malware 1.46 http://filehippo.com/download_malwarebytes_anti_malware/
always update so you have latest database before you scan
click the remove selected button to quarantine anything found
you may post the scan log here if anything is found

Although there are things loading at boottime that aren’t really needed, the HJT log file is clean. The problem is with VLC.
1 Remove it, check manually for leftovers and remove them.
2 Run CCleaner
(Keep running the registry checker till all problems are solved)
3 Run CleanUp
4 Reboot the system
5 Install the latest version of VLC
6 Run the latest version of HijackThis and post a new log.

Thanks,

OK I have done as said, it seems to have helped but the CPU still seems to be fluctuating a lot, nowhere near as high as it was but it still goes from nothing up to 60% and back and everyewhere imbetween… Is there something else I can check?

Attatched is a new hijackthis log.

Thanks again

Ok, fix the following 3 lines with HijackThis
O4 - HKLM..\Run: [QuickTime Task] “C:\Program Files\QuickTime\qttask.exe” -atboottime
O4 - HKLM..\Run: [SunJavaUpdateSched] “C:\Program Files\Common Files\Java\Java Update\jusched.exe”
O4 - HKLM..\Run: [Adobe Reader Speed Launcher] “C:\Program Files\Adobe\Reader 9.0\Reader\Reader_sl.exe”

Open de service manager (start, run, services.msc).
Find the javaquickstarter and set it to disabled.
O23 - Service: Java Quick Starter (JavaQuickStarterService) - Sun Microsystems, Inc. - C:\Program Files\Java\jre6\bin\jqs.exe

This is just to clean things a bit up. No worry, you don’t need those things to load at boottime. Now let’s see about the avi part. You do know there are basicly two kinds of avi?

First one is the old MS avi format. Second one is a “container”. That means it can be about any (movie)file type like mp4, mpeg, avi, divx etc etc. You can check what it really is with a application called GSPOT A true avi file (old format) will play fine. VLC however has some problems with decoding DIVX encoded files since their last update. That is something we can not change. What you can try is getting the latest version of the DIVX Codec and see if that is helping. You may even want to give their webplayer a try. If downloading/installing the codecs is solving the problem, it is nice. If not and the webplayer (or another player) is playing the movies fine, we know for sure it is VLC. In that case we can only wait for a update that solves the problem.
