Prevx on bootup

Re: Introducing, The New Prevx Edge.

Hi,

I've spent several hours today tracking down slow boot issues on PC running a licensed instance of Prevx. BootVis reports Prevx starting about .5 seconds after explorer. During the following 112 secs CPU usage is essential zero, I/O the same with disk usage intermittently spiking (no data volume recorded - paging?), no processes started or drivers loaded.

The scan at boot option was selected. Unchecking it has had no effect after several reboots.

Suggestions would be appreciated.

License key can be provided upon request.

Thanks,

david

 

Re: Introducing, The New Prevx Edge.

Hi David,

Can you tell us what version you are using with what OS and if it is 32bit or 64bit?

TIA,

TH

 

(I've split apart these posts to prevent resurrecting our old, massive thread )

In addition to what Triple Helix has suggested, could you also let me know if uninstalling Prevx corrects the issue? Prevx shouldn't be doing anything system-intensive on bootup, but it might be worth saving a scan log and sending this to us by clicking Tools - Save Scan Results to see if we can narrow down the source of the issue.

Thanks for the help!

 

In case you are looking for the latest Build: Release Candidate

Prevx 3.0 with SafeOnline - Build 3.0.5.64 RC for both 32 and 64bit!

"Never mind."

Thanks for the super fast replies and sorry for my delayed response. Prevx is doing exactly what it is supposed to. The real problem is a Windows Automatic Update bug:

Slow startup with 7.4.7600.226 (The Automatic Updates service hung on starting.) - http://social.technet.microsoft.com/Forums/en/winserverwsus/thread/daf131c5-6a4f-45d1-a03f-c39cea436b6f

It surfaced mid-October 2009. The computer owner started complaining about slow start-ups then. This is the first time I've had the computer long enough for a thorough diagnostic.

Prevx looked guilty because the BootVis trace indicated it was last event preceding a 112 second complete halt in boot processing. I was too tired, lazy and/or impressed with my new toy (BootVis). The plethora of low level detail led me to assume it was a complete.

As I back-filled, in response to requests for obvious omissions in my prior post, a Service Manager error: 7022 stood out. It indicated Automatic Updates had hung at startup. Wall time and time-stamp difference with the prior event (Prevex start) matched. Changing Automatic Update service start to manual (from automatic) eliminated the delay.

Sorry about the false alarm. Prevx was/is respecting option settings, only issuing a FLUSH BUFFERS and not scanning at boot-up.

Roseanne Roseanadana said it all.

 

OBTW.

The Prevx version installed is 3.0.1.65. The system is an HP dv4000 (notebook) P4 1.73 GHZ (PAE), 2048MB RAM - XP Pro SP3 (all updates applied).

Web pages are unclear about Edge licenses including upgrades to SafeOnline. Is it permitted without additional cost? If so, would installing SafeOnline Beta be recommended?

I have questions/comments about Prevx intermittent terminations some silent, some displaying message/balloon and scans aborting without reporting an error. Different topic, different thread.

You can definitely install the newest version - you won't receive the full SafeOnline protection with just an Edge license, but you will be able to add a custom website to the SafeOnline protection and it will automatically protect a handful of pre-defined websites, free of charge, as well as protect any stored cookies + credentials.

It would probably be worth downloading the newest test version from http://info.prevx.com/download.asp?grab=edgebeta and install this over your existing v3.0.1.65 installation to see if it corrects the issues.
