Hey. I was hoping I could get some help again since you've all been so helpful in the past. I have a computer at work, running windows xp with firefox as the browser. Not always, but sometimes, when I click on a link, it redirects me elsewhere. I have run Malwarebytes, spybot S & D, rootkit detectors, and they find nothing. Even reloaded a new Hosts file. I'm stumped. I've been reading online in regards to this issue, and tried the remedies, no help. Any ideas? Thanks.
I use AVG Anti Virus, Registry Mechanic and Ad-Aware for keeping my system clean. I had the same problem you had a few years ago.
Restart your system in Safe-Mode (Press F8 when you see that flashing underscore prior to the XP loading screen)
This way only the basic windows systems will run. While in normal mode, some spyware crap can remain hidded from your scans, which is why it says you're system is clean when it isn't.
Before you run your scans, go into your C:/Temp folder and clear everything out of that. (Some people don't have that folder, if you don't, then don't worry about it)
Second, go into your C:/Windows/Temp folder and wipe everything out of there.
Third, go into your C:/Documents and Settings/
Your User Account Name/Local Settings/Temp folder and wipe everything from there.
The Local Settings folder is generally hidden and you may have to setup your folders to show hidden files & folders.
Once you clear out all of these temp folders, run Ad-Aware (Free program) while in safe mode and do a Full Systems Scan. I have tried other spyware programs before, but they never found as many things as Ad-Aware does.
Once that is done, run AVG and do a full scan for viruses.... all while you're in safe mode.
When you are in normal XP mode, many things in your temp folders won't let you delete them because they're being used. You don't have to worry about anything screwing up on your system from wiping your temp folders, but generally that's where most spyware hide.
Once all that is completed, or while you're waiting for your scans to complete, go into your Firefox, IExplorer and any of your other browsers and make sure your default home page is what you want, ie: Google.ca
After all of that, your system should be clean.
Let me know if you still end up having problems with redirections.
Oh and before you restart out of safe mode, run Registry Mechanic if you have that program.
