That's about right. My advice is: change your AV.

Sorry mate. If I had it my way, I'd uninstall every last piece of AV on my machine. After all, there's IT with their gazillion firewall services to try and block any unsafe EXEs from coming to my machine. Then I have this habit of right-click > Open for all removable drives, so that won't allow any autorun type virii to infect my machine. I wish IT heard my woes X|

I've gone round and round with our corporate IT gestapo over this particular issue. We've recently switched from Symantec Antivirus to McAfee. With Symantec we turned off the real-time scanning and did a full scan every night. In theory this approach wasn't quite as safe, but it reduced our build times from over 3 hours to around 45 minutes. McAfee has given the security goons the means to prevent us from turning the real-time scanning off. I did find a weakness, however. They let me exclude the entire disk drive from the real-time scan, which effectively neuters it. I wish they had investigated this further. I use NOD32 from ESET at home, with its real-time scan feature turned on, and it doesn't suck every last resource out of the machine. Build times increase only a few percent, and it doesn't hammer the disk drive constantly.
Software Zen:
delete this;Yeah ESET is the best in this test ;-) Integrated Firewall is awesome :)

I got into a serious argument with several of the IT admins and decision makers at my old company about the use of Symantec AV. Verdict was that I was right, after a few hours of arguing, providing proof (that already was under their nose) off of the internet but they have to stick with Symantec. No sane reason was provided. I don't work there anymore.

How about format C: \u /y ? just to be sure :) Or even better, why not use FDisk? :)

I've found something similar with the AV software we use at work - the extra disk accessing required by real-time scanning just about doubles build times, especially when you've got 40-50MB pre-compiled header files....
Can you compromise and exclude the location of your sourcefiles from the Realtime options - we have an AV Policy at work, so we live with it but exclude our Subversion Tree.. James

Why is it not scheduled to run at night?
Not sure, but can't find any schedule settings on the client. It has "File system auto-protect" switched on along with proactive threat protection. It seems to scan continuously but tends to slow things down more on fridays than other days.

I had to play a lot with different AV solutions some time ago, and I made a lot of tests, including a real spyware/adware/viruses. So IMHO the Symantec is NOT real AV – this is an application created to hide the viruses and to eat your system resources. The McAfee is really good AV software, but also is very heavy and difficult to use. The best choice on this stage is NOD32, with the shortcoming, that if you need a ultimate protection you should combine NOD32 with some anti – spyware program /scanspyware or something similar/.
The narrow specialist in the broad sense of the word is a complete idiot in the narrow sense of the word.

Dude I have the same problem but at my pc in home what can we do to reduce its CPU hunger?

- Start -> Settings -> Control Panels -> Add and Remove Programes 2) Scroll down to find that yellow beast by its name. 3) Choose 'Uninstall'/'Remove' as is appropriate. 4) Go. Have a beer to celebrate the freedom of your PC.

For some reason, AVG also schedules in the morning hour.

Uninstall Norton. Install decent Anti Spyware/Virus Scanning tools and run them. Keep them up to date and remove any dodgy software you have installed.

WinPatrol is a good one to detect any software that gets installed or gets privileged without your notice like as part of another like RealOne Player setup. http://www.winpatrol.com/[^]

Use another AV software or try to reconfigure the one you have. Move scanning to night and choose not to scan all the files (only executables and script) at realtime. Change the priority of the AV scanner.

I have not seen the 50% CPU usage with that software however I have seen it use almost 200MB of memory split across two of the services it starts. Sadly that is the antivirus that the University has a contract with and thus if we switched we would have to buy something ourselves.

go into the settings for the AV and read what is there and post it here. Once we know what it is doing we can offer advice. Running without AV is not an option here, and I wouldn't recommend it anyhow. However, knowing what you have and what you can do with it rather than just disabling it is a much better position to start with. :) Ours are managed on internet machines, so I can't tune them. We don't develop on internet machines.

When the hell is some company going to come out with hardware based virus protection? Just sit in the bus and look at the bits as they whiz by and throw up a signal to the OS as to what is bad and what needs cleaning...

I'm curious what other people are getting in the I/O Read Bytes and I/O Write Bytes columns in task manager (have to show them with View / Select Columns first). Since IT installed this thing both HDs are hammered non-stop (CPU usage is OK though). Rtvscan.exe is reading about 100 gigabytes and writing about 250 gigabytes per day according to those columns in task manager, which maybe explains why my builds take over 10 minutes....
Mine doesn't read or write anything like that much - maybe 7-10GB/day? But then maybe I don't build as often as you :-) It's still something like 100x more IO than any other process. Oh - and the other thing - it has 18-20 processes open constantly. Doing what? No idea.
