PC too slow after an VirusScan update

Jump to solution

After the last update (06/15/2012) of the McAfee VirusScan 15.0.302 (DAT 6742), my PC has become very slow, and the HDD works a lot. When disabling the analysis in real time, my PC works fine again. 

Which can the cause be? 

I have an AMD Athlon II Dual Core, with Windows XP SP3. 

Thank you.

Thanks for your time, Ex_Brit and Astor.

After the next update of my McAfee Antivirus Plus, the problem was solved by itself.

My system exceed the requirements for the software (4 GB RAM, etc.). And in my Microsoft Outlook Express I have dozens of sub-folders and dozens of rules to classify the messages in the moment in that they are downloaded.

All the other parameters (cleaning of the disk, of the registry, etc.) I also maintain them in good state.

Thank you for your support!

Moved this thread to SecurityCenter.

Did you try a reboot again just to see if it ironed itself out?   I wouldn't recommend disabling real-time scanning as that is what protects you, turning it off is effectively disabling the antivirus component.

You might want to open a case with Technical Support on this as they can troubleshoot it directly.

It's free to reach them by phone or use their online chat and both methods are linked under Useful Links at the top of this page.

I've been having this problem for years on XP, Vista and W7.  It doesn't happen all of the time.  A reboot fixes it.  I'm using an account without Admin privs.  I also believe this problem has been reported many times before so McAfee should be well aware of it.

Make sure the machines meet or exceed (preferable) the minimum requirements for the software (see below).  Do regular cleanouts under Control Panel/System and Maintenance > Disk Cleanup.

If you are in the habit of storing emails in your Inbox, don't, make sub folders for that purpose.  That can slow things quite a bit.   Make sure all aspects of your system are up to date, especially IE, even if you don't use it.

I presume you mean don't make sub folders inside the Inbox.  I have dozens of folders elsewhere.  That's best prractice for handling large amounts of email.

Yes that's what I meant.  Sub-folders of the Inbox would still be the Inbox by any other name.
