This stinks!!! IT just had a guy sent over to "upgrade" the antivirus on my system. He's done installing the AV software, I reboot the PC, and the next thing I know RTVScan.exe is eating up 50% of my CPU. :mad: X|

I assume thats the initial "Scan all hard drives" workload. Should be over in a few hours (depending on your machine). Robert

Your CPU must be really tasty and/or the AntiVirus very hungry.
No chances of the former. Three years of accumulated dust does not help make something tasty, does it? ;P

Yeah, I get a taste of it every 4 weeks or so when I clean the heat sink with canned air.

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....

Hmm...sounds tasty. I wonder how it goes with fries. :laugh:

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....

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

Unplug your Internet connection.
Mostly, when you see programmers, they aren't doing anything. One of the attractive things about programmers is that you cannot tell whether or not they are working simply by looking at them. Very often they're sitting there seemingly drinking coffee and gossiping, or just staring into space. What the programmer is trying to do is get a handle on all the individual and unrelated ideas that are scampering around in his head. (Charles M Strauss)

Install more CPUs.

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

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.

Start - Run - cmd.exe Then type
FORMAT C: /Yand hit Enter. CPU usage will be down to 0.Cheers, Vikram.

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 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? :)

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

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.
