Endpoint Protection

Since yesterday the Symantec Endpoint Protection on my window XP repeatedly give an error message "SONAR Component has encountered a problem and needs to close.  We are sorry for the inconvenience".  Then the Proactive Threat Protection becomes disabled, wrongly stating that "Protection definitions are too old for Proactive Threat Protection. Click Fix to update prtection definitions." Of course the definitions are updated, but the Proactive Threat Protection simply remains disabled.

I found an old thread (https://www-secure.symantec.com/connect/forums/sonar-component-error) and realized this is a time-worn issue. Apparently it's come back again. Would anyone please come to my rescue? Thank you so much!

What version of SEP is this?

Have you tried running a repair on the client?

Did you try a re-install?

The version is 11.0.2000.1567.

I can't find the repair option. Would you please tell me where to locate it?

The install disk is not available now and I wanted to explore other available options first. The old thread reflects that reinstallation didn't help.

Thank you very much again!

First off, that is a really really old version, from about 2009 I think. It was one of the first versions of SEP 11.x and thousands of bugs have been fixed since than. Do you have any way to upgrade to either SEP 11 RU7 MP3 or SEP 12.1.2? An upgrade would likely fix this.

If you go to add/remove programs and select the SEP install, you should be able to do a repair from there.

This is really a SOS. I followed the instructions and tried to repair the SEP. Everything went fine, including passing the harddisk space check. But it started to build the "install cache," my free 2G space was quickly consumed and the repair stopped doing things. When I restarted the system and freed up more space for repair, it consumed my another 2.5 G space. My harddrive is being swallowed up and even though I interrupted the repair and had it restarted, it didn't free up the space it swallowed before. Now I lost 4.5G and am on the verge of a total system down.

Would you please help me delete the unwanted "install cache"? I have tried everything, including Disk cleanup and CCleaner, but to no avail.

Ultimately, how much space does the SEP repair actually require? It constantly says my diskspace okay but ends up using all of it without completing the task.

Thank you so much again. I really appreciate your greatest help.

Did yu try the disk cleanup feature in XP as well to see what it can remove?

That's the first thing I tried. It has cleared up all temp and catalog files. But 4.5 G I lost is never recovered.

I freed up another 4 G space by compressing the old files through Disk cleanup. But before learning how to get back the lost disk space and how much space exactly the SEP Repair requires, I dare not proceed again. I don't know whether uninstall the SEP would even help now.

The easiest way I imagine would be I could learn where the install cache is located and how to kill it. I would deeply appreciate your further advice.

Problem solved: by jumping off the ship.

1. Uninstall the SEP. (I took further caution to use Norton Removal Tool to eliminate all the un-uninstallable Norton monsters eating up my disk space.)

2. Then run CClear to clean up the harddrive. This time I gained back all my 4.5G.

3. The "SONAR Component" error was also solved by simply dropping and staying away from the SEP and replacing it with a third party no-hassel security software.

4. Conclusion: Don't ever try to "Repair" the SEP if anything goes wrong. It makes things worse.
