Slowdown of Microsoft Visual Studio due to different Virus scanner

Question

What is the least slow Virus scanner to use with Microsoft Visual Studio

I have just had Microsoft Visual Studio “go slow” on me again due to my Virus Checker… (100

Answer 1

We have Trend Micro antivirus at work, and it's terrible. It seems particularly bad doing checkouts.

We commissioned a new build machine recently, and the IS team hadn't set up exclusions for the build drives, and it was taking 45 minutes to check out source code from TFS. With the AV turned off, the exact same source code took about 1 minute 30 seconds to check out.

Answer 2

Having Fusion assembly binding logging enabled in combination with a virus scanner can result in performance problems during startup of an application. Either disable the Fusion logging or add the folder that it logs to as an exclusion in your virus scanner.

Answer 3

Don't use Kaspersky(The old Tect Review one) it slows down normal explorer file opening for almost 10 second(Yes, you need to wait 10 second before opening each folder). And yes it affects Visual Studio. The new version does not seem the have the problem. NOD32 seem to not have this problem, and is a bit faster than Kaspersky(I don't even know if it's scan as much as Kaspersky does).

But for what ever reason, NOD32 firewall is bad!

Answer 4

I'd have to agree with the first answer.

I've seen such issues differ between jobs according to the verocity of the admins' intent to leave configs unchanged for devs. Correctly setup virus scanners still hinder dev, but at least it's bearable.

So I edit the scan lists to:

• Exclude all dev code directories
• Exclude Temporary ASP.Net gen'ed areas
• Exclude Resharper caches

I find this improves the disk thrashing that otherwise occurs with Visual Studio, Resharper and a Virus Scanner all hammering the drive. As always SysInternals' Filemon can help you target rogue services/processes.

Answer 5

I haven't really done any measurements, but what I usually do is to exclude the real time scanning of my development folder (usually my :\Projects folder). That way, the compiler can work as fast as possible during my everyday repetitive tasks. I do have a daily scan that have the folder in question in its path, in order to fetch any possible threat. On a subjective note, I prefer to use NOD32.

Answer 6

Well to be honest, my work machine doesn't have a virus scanner installed, and for almost 2 years, I've never had a problem with viruses because I'm constantly behind corporate web patrol and other things keeps me pretty safe.

At home, though, I use NOD32, and on 3 different machines all using Visual Studio, I've never noticed any slowdowns. I apologize for not having any benchmarks to measure, just wanted to throw out my "answer."
