windows Annoying connection problem

[Nik00]

Sorry for my post in ET problems, i noticed have a global connection problem. so here's it: for the second time, i suddently have slow connection. i mean, i usually have a 7 Mbit/s connection that always worked good. the problem is that it goes suddently to about 8-15 Kbit/s, and stay like that, and it's impossible to surf the net like that, it takes hours to open the white google screen ._. I do think it's a virus i caught, but antivirus (Avira Antivir) didn't found it even with full pc scan. the first time i had this problem, i solved it with a format of hd, but this time it seems don't working...reset pc/connection doesen't work.

 

It's not isp or connection problem, cause now i'm on my 2nd pc (that really sucks and i can't play et) and it works well, but i think is pc problem.

 

 

Anybody of you guys had this problems and knows how to solve it?

 

sorry if i explained it bad, ask for every question that could help..

 

Thank u all

After the 2nd format it didn't work..but after about an hour, i quite desperatly started internet and it works, but i wonder how long will it...

 

any advice is well accepted

[-=Medic=-]

try eset nod32 free trial and see if you find anything (don't forget to update before scan) http://www.eset.com/...ownload_int.php

 

also download TCP Optimizer ...

 

Scroll "connection speed" to your real speed, i dunno something like 7500kbps

 

Mark "Modify all network adapters" and Mark also "Optimal"

 

in "MTU" put value 1480 instead of 1500

 

Don't touch anything else. Hit "Apply changes"

 

it's gonna ask you to restart your PC, say OK
