Forum Thread: High Cpu Usage on Windows 7

Hello mates,

I've been using windows 7 home basic 32bit. my laptop cpu usage is always full since last two months. It's getting worse everyday. I can't even watch a hd movie. typing also getting slow. i've tried many antivirus(trial versons), and installed zone alarm firewall. scanned with some cloud based antivirus also.

I can't find any virus. sometimes malwarebytes anti malware alerted inbound traffic to svchost.exe on multiple ports. (i ve scanned scvhost.exe on virustotal. The result said it was clean.

someone help me please

SOL man, but see about getting any data you need and wiping/reinstalling Win 7.

You are definitely infected!

Have you been doing any downloading from P2P sites?

i've been torrenting new movies.

You have torrented a rootkit that is now embedded in your system files.

Follow oaktree's suggestion.

I can't find any virus. how to remove without even identify the virus?

Part of what makes a rootkit a rootkit is that it hides itself from the programs that show you what files are on your HDD and what processes are running.

how to find that rootkit? i've scanned with multiple antiviruses, it may be a zeroday. If i find it, i can also use it on the wild.

As oaktree said, it is embedded likely in your system files. AV won't find it.

Should probably head over to a professional forum and get a second opinion. Though what you describe are the symptoms of malware infection, you may need to know how severe a potential rootkit could be. In rare cases, formatting your disk may not even solve your problems and you could have covert malware stealing your information despite you thinking that your system is clean after a reinstall.

The question is: "Can you risk it?" You may want to consider a worst-case scenario here if you're using the computer with sensitive information.

Try to be more cautious the next time around.

I don't understand why @chentox was downvoted.BleepingComputer is a credible resource for malware removal and computer problems in general.And as @dontrustme suggested,you should head over to a professional forum.I suggest you should post your malware issue over BleepingComputer's forum that deals with malware.They are really useful.

I don't mean to be rude or anything but playing with malware isn't a game. Some people don't understand the the tricks and sorcery they use to survive in the wild.

It's not guaranteed that you'll find the malware responsible for a damaged system. Besides, who knows if there more malware lurking elsewhere that's not running? Any sign of malware means that there is potential to be more malware, even worse ones than the initial infection. If it were that "easy" and "foolproof", why do professionals in this topic even exist?

Sure, you found a malware running as a process, identified it with VirusTotal and manually deleted the file on disk. What happens when it comes back, right after you restart your computer, or even straight after you remove it? What about infected system files? How would you remove that? How do you know if there's a rootkit feeding you incorrect information?

Format your drive and reinstall your operating system just to make sure the malware is gone? How will you know that you've removed the rootkit? What would you do if the rootkit has gotten into your BIOS and persists even after operating system reinstalls? Where is your God now?

Don't try to be a hero, let the specialists handle what they specialize in. You could end up doing more harm than good.

And clickbait is clickbait.

Well explained dontustme.Amen to that.

You are right. I am no expert and that is why I prefaced it with: " I am not sure if it is apropos but I thought i would link it.". The guy who wrote the article is, in fact, an expert. I am just basing that on the fact that he holds 40 certificates and authored 8 books.

Yes, yes. I'm aware of the author-of-the-article's supposed credentials however knowing the behaviors of malware and posting clickbait like that is a problem in itself. He knows it's not foolproof, I know it's not foolproof, he should know better, shame on him.

To be fair to him, it does say 'Almost' :). Though i get your point.

I found the trojan on my Huawei e303f datacard. I tried to install it on another laptop, which is having Baidu AV. Baidu found the virus, but doesn't remove it.

How to remove this trojan?
