Hi,
I have an issue with some sort of search engine redirect infection.

It was coming up with every first click on a link found by google (if I went back and clicked again the correct site would come up) when logged into windows 7 as myself (I have set up my laptop so that neither I nor my husband are admins, but I have a seperate admin account after a horrific virus last year). It had been affecting firefox, but I didn't try ie or google chrome.

After reading several different things I tried running Trojan Remover, which found some files, details below (not the whole log).

This didn't cure the problem though and every time I opened firefox it wanted to run a firefox.exe file from a dodgy location (same app data\roaming as above), which I didn't allow.

I then ran combofix, which deleted the firefox.exe file and another one (can't find log). When I opened firefox or ie they didn't work immediately however as they were defaulting to a proxy server which no longer existed, so I fixed that.

Now it no longer redirects me to another page when i click on a link from google, but in the process bar it seems to be getting info from lots of weird websites before 'done' appears, and so I'm worried that it's doing something dodgy in the background?? Thoughts?

thanks,
Helen

Edited to say: today when I opened firefox I got another message asking me to run firefox.exe so I guess it still hasn't gone. I'm no longer being redirected but I can still see it trying to redirect me almost, by referencing other websites in the process and address bar.
