Port 80 windows 7 ???

Imam prplem.. na računalniku imam naložene:
windows 7
AVavst antivirus

problem imam pa v tem da mi je kar nal lepem nehal delovati možnost surfanja po internetu (port 80)

maile lahko prejejmam...

internetna povezava deluje normalno...

vendar z IE ne morem na nobeno stran
z firefoxom tudi ne morem

probal sem ping www.google.com

deluje uredu (26 ms)

pregledal sem vse firewalle, nastavitve....

kaj naj naredim
??

Verjetno je problem s firewall-om. Tole je iz avastove strani:
Q: I have installed avast! and I can no longer browse the Web. How can I solve this?
A:
Check your firewall configuration. For the correct operation the Web Shield process (ashWebSv.exe or aswWebSv.exe) needs a permission to access the Internet (TCP port 80) and a permission to act as a server and accept incoming connections from localhost (the local machine) on TCP port 12080.
