Hello, Two weekend ago I noticed my laptop running super sluggish on the internet and I also noticed the CPU usage was 100%. To combat the issue I ran a "Disk cleanup", a "Disk defragmenter" and a Norton Antivirus scan (clean). I removed any programs that I didn't use any more and lastly went to the startup folder to disable some programs that might get the CPU usage down. None of that worked as my usage still went up when I opened any programs and especially when on the internet. Searching on google and several posts mentioned that it might be malware. Several post also mentioned that "Malwarebytes" was very good at finding and removing malware. I downloaded it in safe mode and ran a full system scan. After 1hr and 20mins it found a suspicious file that was quarantined and deleted. When I tried to restart my laptop normally everything locks up/ freezes when the Desktop tries to load. I had to put the laptop back in safe mode and do a system restore to get it to work when normally booted. Of course parts of Malwarebytes are uninstalled because of the restore point time and the suspected malware is put back where he was! I tried once more in safe mode with "RKILL", "TDSSKiller" and Malwarebytes but got the same result. Finally I posted in the "Am I infected" forum on bleeping computer and got very good help. The moderator said my system seems clean after he had me run several scans and removed 1 malware infection. He then told me to repost in this forum to get help with the "high CPU usage" issue.

I thought the CPU would go down after I got rid of any infections but the CPU is still 100% on the internet and close a 100% when running certain programs. I appreciate any help with this problem! Hopefully I will not have to buy a new laptop.
