Hi,
Since last night when I was searching for a TV link for the Spurs game my PC keeps opening chinese pages automatically. My homepage had been reset to www.sha123.com and the page that keeps opening now is removed.
I also had a google style toolbar [in chinese]appear and new chinese description option in my internet options and programs.
I have unticked all the chinese options in internet options.
I ran AVG free edition, spybot and adaware. Adaware found a lot of problems and after fixing it said 4 items could not be removed without a reboot. I rebooted and ran adaware again but it did not find the problems again!
I have also tried a system restore to several points before last night but it just keeps saying cannot restore to that point.
Any help would be appreciated,

Regards,
Alan

You should never post a link to a suspicious or bad site. Please edit and remove.
Below is a link Avg 7.5 antispyware. download, install, update and run in safe mode. Allow it to quarantine whatever it finds.
Check your Add/Remove list for suspicious entries. Do not remove them unless you are sure what they are. You can Google any you are unsure of.

If AVG doesn't get rid of the infection I would suggest you post a Hijack This log by following the directions in the link below.

OK, sorry for the link. I've run the AVG spyware which found a lot to quarantine but the web pages still keep opening, different ones now but all in chinese - or Japanese maybe - and it changes my homepage to sha123. I've followed the hijack this procedure and posted the log below. Many thanks for any help you can give.
