I have noticed that avast slow down google chrome on one of my computers. If I disable avast file shield and web schield google chrome seems to be faster. The strange thing is that on the other two systems of mine google chrome works goodwith avast. Can anyone tell me if avast could be the cause of this slowness? If yes, what can I do to prevent avast to slow down my browser? Please help me
what other security programs installed?
have you removed leftover files from previous used AV programs ?
I have always had avast as antivirus…
was your computer(s) delivered with a preinstalled trail AV when new ?
No, there wasn’t any AV preinstalled.
is avast blocking my browser? How can I do to prevent avast free from blocking chrome?
No one can help me??
avast! free does not block chrome. avast! doesn’t have a firewall. avast! free scans your internet activity.
The only thing it blocks are infections and infected websites.
I’m using Chrome and avast! free.
What firewall are you using ???
I use the windows firewall integrated in my windows xp, I haven’t got any other firewall
What error messages are you getting ???
when I open google chrome and I try to open a web site the browser shows me a white page, I see only the hourglass of chrome, which symbolize that the browser is trying to load the page…after about 3 minutes appears the error message " the page cannot be found"
Is that for all websites or a particular website ???
Which Website ???
Have you tried the same website in another browser ???
I have tried with firefox an IE and all works good. Chrome gives me the same error on all the web sites I visit, also on facebook, the avast forum, exc
Which version of Chrome ???
Have you tried disabling all of your extensions to narrow down the problem ???
If it works without the extensions, then you’ll need to isolate the culprit that’s causing the problem.
When was the last time that you cleared the browser data ???
I have the last version of chrome, number 21.0.1180.89 and the only extention I use is the webrep plugin of avast. If I disable it the situation remains the same. I always clean the cache of chrome with cleaner, I do it each day
At this point, I have no ideas as to what’s causing it.
I use Version 22.0.1229.64 beta-m without hesitation.
You could try a clean install of Chrome but I don’t know if that would help.
Sorry.
I have tryed also to reinstall it, with no benefits 
Stop the WebRep to feel the speed of surfing!
I had huge delay with the stable version and this additional protection a long time ago
If you had read selen’s replies, you would have known that disabling WebRep made no difference.
I have WebRep and a few other scanner add-ons and am not having any slowdowns in Chrome.
I have just turned WebRep on again and it is ok no delay - more safety now.
Chrome stable > 21.0.1180.89m
Thanks for your reply
