i had installed avast 4.8 before too but within twp days i was not able to acee the web the
ie displayed the page cannot be displayed everytime.
then i removed avast and installed google pack which came with norton security scan and spyware doctor then i visited avast forum and found the solution
i then downloaded the 4.8.1169
then i configured the pc shown in instruction video how to set proxy server ms ie explorer lan
i also added the three processes to the windows firewall which were mentioned in the forum
since then the internet has not disconneted but the speed has slowed down not much though
but recently i have encountered few different problems
if i disable the on access scanner the web gets disconneted also some windows settings gets channged
automatically
.eg. the check box in display settings for show windows content while dragging gets unchecked i have to configure it again also the fonts gets changed also i think worth mention
is in the log file after the scan for every file it scan is written
eg.Exception in polymorph virus code(421000)
no matter what file it is then
i then upgraded to 4.8.1178 but still the problem does not solve
that are few problems
