Title: Avast 5.0.377 high CPU in some webpages
Post by: Martinss on January 24, 2010, 05:28:52 PM
Hello guys, in following websites avast begins to consume between 20 and 30% of system resources and it freezes for a few seconds, this does not happen if I deactivate all the protections.

Windows XP SP3 with all updates.

webpages:

www.cariverplate.com.ar
www.riverplate.com

please check this with your systems ;D

The two are effectively one and the same as riverplate.com.ar redirects to the first link.

I'm only on dial-up and whilst the first site is relatively media rich, it didn't take long to load and I noticed no spike in system resources. It also has a number of cross site scripting which can also slow loading and or increase resource use as that will also be monitored.

I use firefox 3.5.7 with NoScript which blocks scripts by default (temp allowed cariverplate.com.ar) and also RequestPolicy (blocks cross site access unless allowed) add-ons, so thes may also have improved my experience.

What browser/s are you using and is this the same and is the same across all browsers ?

What other security software do you have installed ?

test in firefox 3.6 with adblock extension only , google chrome v3, internet explorer 8 and I have no other security software.

PD: sorry the second page is www.riverplate.com not .com.ar, fix in the first message  :)

This site is very heavily loaded with media so takes much longer to load, but again I'm seeing more memory used (understandable as all this stuff is being scanned) but negligible increase in CPU.

So unfortunately I'm not experiencing what you mention.
