hey, I'm running windows 7 64-bit and im having some trouble with my cpu usage. it jumps up and down even when idle. The main sources of the usage is: conhost.exe, svchost.exe, msiexec.exe, taskhost.exe and others each using an unusually large percentage. Every time I end the process they just restart again a few seconds later.
 

I have ran several scans with Microsoft security essentials, the first scan came up with 3 infections. I removed them and scanned again. another 3 were found and removed. a third scan showed 1 more infection and this was also removed. all 7 infections had the same name just a different variation of numbers at the end of the names (possibly different locations). I have since scanned another 3 times and no threats have been found, but the problem still remains.

 

I have also ran combofix. This hasn't fixed the problem but im not good with logs so maybe theres something in there. (can be re-scanned and posted)

ive also tried a few recommendations from other peoples posts about similar problems. tdsskiller.exe, adwcleaner.exe and securitycheck.exe.

 

none of these seemed to help either. if these produce logs I can re do them and post log.
I already have the securitycheck log:

 

 

 Results of screen317's Security Check version 1.009 
 Windows 7 Service Pack 1 x64 (UAC is enabled) 
 Internet Explorer 11 
``````````````Antivirus/Firewall Check:``````````````
 Windows Firewall Enabled! 
Microsoft Security Essentials  
BullGuard Antivirus            
 Antivirus out of date! (On Access scanning disabled!)
`````````Anti-malware/Other Utilities Check:`````````
 Java 8 Update 51 
 Java version 32-bit out of Date!
 Adobe Reader 9 Adobe Reader out of Date!
 Mozilla Firefox (42.0)
````````Process Check: objlist.exe by Laurent````````

 Microsoft Security Essentials msseces.exe
`````````````````System Health check`````````````````
 Total Fragmentation on Drive C: 0%
````````````````````End of Log``````````````````````

 

Any help with this would be great, I've been stuck with this for nearly a week now :(

(if your recommending any file downloads please note the application name and source next to the download link, thanks :)

(( by the way I don't have any money for paid downloads like malwarebytes, I know you guys like to recommend that one ;))

Welcome aboard p22002758.gif

 

p22002970.gif You're running two AV programs:

NOTE 1. If one of your security applications (e.g., third-party firewall) requests permission to allow DIG.EXE access the Internet, allow it to do so.
NOTE 2. SecurityCheck may produce some false warning(s), so leave the results reading to me.
NOTE 3. If you receive UNSUPPORTED OPERATING SYSTEM! ABORTED! message restart computer and Security Check should run

p22002970.gif Please download Farbar Service Scanner (FSS) and run it on the computer with the issue.

  • In most cases, a restart will be required.
  • Wait for the prompt to restart the computer to appear, then click on Yes.

p22002970.gif Please download Rkill (courtesy of BleepingComputer.com) to your desktop.
There are 2 different versions. If one of them won't run then download and try to run the other one.
You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

rKill.exe: http://www.bleepingcomputer.com/download/rkill/dl/10/
iExplore.exe (renamed rKill.exe): http://www.bleepingcomputer.com/download/rkill/dl/11/

  • Double-click on the Rkill desktop icon to run the tool.
  • If using Windows Vista, 7 or 8 right-click on it and choose Run As Administrator.
  • A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
  • If not, delete the file, then download and use the one provided in Link 2.
  • Do not reboot until instructed.
  • If the tool does not run from any of the links provided, please let me know.


If normal mode still doesn't work, run the tool from safe mode.

When the scan is done Notepad will open with rKill log.
Post it in your next reply.

NOTE. rKill.txt log will also be present on your desktop.

NOTE Do NOT wrap your logs in "quote" or "code" brackets.
Do NOT use spoilers.
Do NOT edit your reply to post additional logs. Create new reply. I'll not get any email notifications about edits so I won't know you posted something new.
