    Slow browser, slow internet, random audio ads: virus?


    So yeah, I've these problems for the past couple days. My browsers (Opera and Firefox) used to load pages quickly, but now they're painfully slow. Opera lags and freezes often; Firefox doesn't, but it still takes a very long time to load pages.

    I'm also getting these occasional "invisible ads," even when I don't have a browser open. I can hear the ads but I can't see them.

    Also, I sometimes get redirected to unwanted sites. This mostly happens when I click on a search result in Google.

    Here are some things I've done:

    -Ran SUPERantispyware (I can post the log(s) if needed)
    -Defragged hard drive
    -Cleaned cache, cookies, etc. on both browsers

    Hi solarmystic, thanks for replying.

    Ran CCleaner.

    Just ran MSE - no threats found.

    Ran MalwareBytes - no threats found. I also ran MalwareBytes a couple days ago but it didn't fix the problem, even though it removed two threats. I'll post that log below.

    is possible that you picked up a 'roofkit'

    here's a link to a useful utility to scan for and remove rootkits

    Hi tman,

    I downloaded Blacklight, but it looks like it isn't compatible with Windows 7.

    Hmmm, for some reason none of the files I downloaded will open. I tried opening the .exe files for Dr.Web Fixit, TSDDKiller, and Avast!, but no luck. Is the malware preventing me from opening them or something?

    this may help kill any running processes

    Rkill - Repair Tool of the Week - Technibble

    also you could try starting your machine in 'safe mode' and then you may be able to launch the program(s)

    Ran Rkill (as a .com file) - it didn't find anything.

    The antirootkit files I downloaded still won't open (even in Safe Mode), but other .exe files work (Guild Wars setup, for example). I did manage to get Dr.Web Cureit running, but it didn't detect any threats.

    And just as an update, I'm still experiencing the problems I mentioned in my original post - Google results redirecting me to unwanted sites, laggy/slow Opera browser, and slow-to-load Firefox browser.
