    Performance Issues, Incompatibility with VS2010/Sharpdevelop

      Hello,

       

      recently (since today), I'm having heavy issues with the performance of the virus scan. In typical messenger programs (like Miranda or Skype) i receive a high CPU-usage on keyboard input. It goes up to 12% (Which is high, as a Core i7-2600 has "8" virtual cores, which means one is almost at 100%). This issue can only be fixed by turning auto protection off completely.

       

      Another point i want to mention is the incompatibility with VS2010 or SharpDevelop. Both IDE's are affected negatively by a running auto-protection.

      In VS2010 Ultimate: Various controls cannot be edited (Properties disappear, Known elements don't update at all), which can be solved be disabling.

      In Sharpdevelop: One needs to turn off the "File Change Check" under options or otherwise the IDE's graphical GUI editor will just flicker all the time, trying to reload the file.

       

      One more thing, I'm a student and therefore a "home" user. Then why isn't there even a option to exclude directories from being real-time scanned? I don't get it.

       

      Have a nice day. I hope to receive some helpful answer soon or otherwise I'm forced to change the protection suite to a competitors product.

      Mike

            Well here are the details requested:

             

            McAfee SecurityCenter:

            Version: 11.0

            Build: 11.0.608

            Version of Boot-DAT-File: 6474.0000

            Scan-Moduleversion: 5400.1158

             

            McAfee Personal Firewall:  (anyways disabled)

            Version: 12.0

            Build: 12.0.344

            Last update: 19.09.2011         

             

            Operating system:

            Windows 7 Ultimate, Service Pack 1, German, 64bit

             

             

            The process which creates the CPU-Load is: "mcshield.exe"

             

            My realtime scan is configured as following:

            - only applications and documents

             

            Then next:

            - E-Mail attachments is the only checked thing

             

            Threats:

            - Cookies

            - Scripts

            - Spyware

            all checked

             

            Extended Protection:

            nothing enabled

             

            Drives for Media:

            - Ask before doing extensive scan

             

            It seems like mcshield.exe is somehow hooked into the keyboard input directly. As when i type, the keyboard response time is really high. Which means i type a sentence and it takes like ages for the text to appear (char for char, not at once).

            I have made a screencapture of this, so you can see it live: http://www.kufi.net/problemvideo.mp4    (best played with VLC).

              another update:

              The keyboard thing only happens, if the window containing the chat, is unfocused and refocused (for example clicking the browser while chating, and then switching back). If i close the conversation and reopen it, the problem does not arise...

              Very strange thing going on.
