I just updated Trend Micro to Titanium. Since then something called coreserviceshell.exe is consistently consuming 40%-50% of the CPU processes. I haven't found a solution that has worked for me in the knowledge base after a few hours of fishing around. Can someone point me to the right direction? Thank you. I have an Acer AMD 64 processor...

Base on the Support cases we have received CoreServiceShell.exe causes high CPU/Mem usage due to the following:
1. Conflicting security software.
2. Low system resources - only happens when browsing media heavy websites.
3. Malware infection.

Chaste02,

Can you please be a little more specific? What security software? What malware infection? Do you have any specific examples that might help to troubleshoot the problem?

[chaste02]

For Trend Micro Titanium Antivirus+ we need to make sure that there's no security software which provides antivirus and antispyware feature.

For TM Titanium IS and Max Security we need to remove security software that provides antivirus, antispyware protection and internet security (Spam Protection, Parental Control, Malicious Behavior Monitoring, Web Protection).

For malwares, most Fake AV variants and other malware which frequently access the web can cause high cpu..

It can also be encountered when your Available Physical Memory is 100MB below.

What we usually do is to manually look for conflicts in Add/Remove programs. For malwares we run Trend Micro free tools, Housecall and Rootkitbuster. If your issue only happens when browsing and have low memory, Support Team can provide a hotfix.

Hope this helps.

Hi Chaste,

Thanks for that.

I've had a look through my add/remove programs and couldn't see anything obvious that would conflict with Trend. I'll run a malware/Virus scan tonight, to see if anything comes up.

The coreServiceShell currently consumes around 3-10% of cpu at any one time, and can spike to 100% on occasion. I'm pretty sure it's Trend, as the problem disappeared on uninstalling trend, and re-appeared after re-installing.

It's causing me more irritation than anything else at this stage, but I'd appreciate any info that could sort it out.

Cheers

Matt
