100%CPU Usage

Recommended Posts

Hello there. I am using HP pavillion dv6 core i3. my cpu usage shoots to 100% even if no processes are running. Sometimes it becomes normal after 15 to 20 minutes but when i open browser again it shoots back, even though i havent opened any website yet. If i play any video ,either on internet or windows media player or any other software, i face same problem. please provide me with the solution . initially i thought its becuase i dont have enough space in windows drive but now have 95GB still i m facing same problem.

Hello and :welcome: , piya:


Please follow the steps below to run the DDS scanner.

The please post back here with both logs attached to your next reply.


They will give the staff/experts a bit of info to help to determine the cause and possible solution for your issue.







DDS Instructions

Download DDS from one of the locations below and save it to your Desktop:

Once it is downloaded, you can disconnect from the Internet and disable your Ant-Virus temporarily if needed.
Then double click dds.scr or dds.com to run the tool.
Click the Run button if prompted with an Open File - Security Warning dialog box.
A black DOS console should open and run for a moment.

  • When done, DDS will open two (2) logs:

Hello and Welcome to Malwarebytes

Being that you are infected, feel free to follow the instructions below to receive free, one-on-one expert assistance in checking your system and clearing out any infections and correcting any damage done by the malware.

Please see the following pinned topic which has information on how to get help with this: Available Assistance for Possibly Infected Computers

Thank you

Also, just a note that you have two Anti-virus Programs Running Simultaneously (AVG AntiVirus Free Edition 2013 and Microsoft Security Essentials)

I do not recommend that you have more than one anti virus product installed and running on your computer at a time. The reason for this is that if both products have their automatic (Real-Time) protection switched on, then those products which do not encrypt the virus strings within them can cause other anti virus products to cause "false alarms". It can also lead to a clash as both products fight for access to files which are opened again this is the resident/automatic protection. In general terms, the two programs may conflict and cause:

1) False Alarms: When the anti virus software tells you that your PC has a virus when it actually doesn't.

2) System Performance Problems: Your system may lock up due to both products attempting to access the same file at the same time.

Therefore please go to add/remove in the control panel and remove either AVG AntiVirus Free Edition 2013 or Microsoft Security Essentials. I recommend you remove Microsoft Security Essentials as it no longer is considered and effective anti-virus program.
