After updating to 4.8.1335 internet is slower

[Avasthigno]

After updating to 4.8.1335 surfing and downloading are significantly slower. When I turn off on-access protection internet works normal. Does anybody have the same problem? I will reinstall avast! later to see if it can help.

I see no such slowdown, but I'm on dial-up so I have varying degrees of slow already.

No problems here. Vista x64 and 4096/1024 connection.
What browser are you using?

[Avasthigno]

Firefox 3.0.6

Download is decreased from 180 Kb/s to 30-40 Kb/s.

Reinstalling was not of help.

Try stopping the Web Shield. Does that make any difference?

And what about the Network Shiekd?

[Avasthigno]

When I stop the Web Shield surfing/downloading is normal. No problem with Network Shield.

What if you only pause the Web Shield, as opposed to stopping it?

After reading this topic I checked my download speed which was 4888kbps with the Web Shield running and 4936kbps with it paused (upload speed remained stable), whilst it may affect those with slower download speeds I feel its a small price to pay for the protection you would lose with the Web Shield turned off.

I do not see a reduction in speed with the update but then I do not have a software firewall installed other than the XP firewall.

I am sorry for the late response.

When I paused Web Shield the internet still was very slow. In the same time on my notebook I have avast! 4.8.1296 and there was no slowing.

Finally, the problem disappeared as it come and now everything looks OK. I will watch what will happen in the next fiew days.

Thanks for helping. Best regards.

Slightly (or perhaps more than slightly) O/T, but related ...

I presume that the new malware-url database associated with Network Shield  will grow as new sites are added to the defs.  Is it possible that database-lookup contributes significantly to slowness when browsing?

Hardly. A lookup to the URL database is several orders of magnitude faster than the actual virus scan.

I'm on high speed cable internet (Cox), cable internet is unstable.  I often get wide variations of speed from speed checks, I use Speakeasy to check the speed of my internet.  Due to the unstable nature of cable the data I'm giving isn't very credible.

With Web Shield disabled I get up to 25mbs download.  With Web Shield running I get up to 18mbs.  It doesn't make any difference if it is paused or disabled.

Network Shield on or off makes no difference.

I have gotten 27+ mbs with Web Shield on, but it's been quite a while.  I believe it was with 4.8.1296.

I have seen no difference on the three computer which I have. The main one is Vista and the other two run XP.
