can not open any web page after installing avast8

help, one of my computer can not open any web page after i install avast 8 free version, the system is windows xp sp3 and browser is ie8, and i also tried tencent browser 7.3(which uses ie 8 kernel) and the result is the same. whenever i open a web page it says the connection is reseted. i’ve tired restarting my computer and things not solve. i also tried to reset ie setting(both in ie options and avast tools) but not works. i can access web pages after turnning off web shield in avast so this is something related to the web shield module i think. i tried to change the action of web shield for virus/pup/suspicious to ask and nothing prompt when the web connecton is reset
the program version is 8.0.1489 and the definition version is 130531-1, can anyone help me to resolve this problem? i don’t like to leave the web shield off

  • Other security related software installed…??
  • Which AV did you use before avast!..??

currently no other secury related software installed

360 antivirus(an antivirus software in China) was installed before avast, i’ve uninstalled it and rebooted before installing avast 8
i think my issule may be related to 360 av as it really has a bad name but i just don’t know how to resolve this problem

Maybe. Unfortunately I don’t know of a removal tool for this AV.
Wait for someone else to offer advice or try to find one on Google.

is it IObit Security 360 ?

IObit removal tool should Clear any leftovers… see Nr #17 http://singularlabs.com/uninstallers/security-software/

there is also Norton 360. You can find its removal tool from here:

Just in case you had Norton installed before IOBit.
