Something keeps downloading viruses to my computer and changing google search links to unwanted sites?!?!?

Whatever it is keep downloading viruses and 'XP internet security 2010' malware to my computer. Whenever I get rid of all the viruses using Malwarebytes Antimalware in safe mode, the link changing and popups don't stop but all other viruses are removed, only to be reinfected a short while later!?!?!? This is killing my Pc... please what is it and how to I stop it?

Edit:

Why spend 30-40 min off you're time using a booting CD, Malwarebytes is the most effective anti malware tool out there and doing this 10 min guide at the MAX will solve it :)



You have morelikely come across a Trojan Dropper which downloads unwanted files such as XP internet Security. This is a very easy process if you bare with me. This should be a 10 min fix if you do exactly as I say.



1. Locate an non-infected machine



2. Locate an USB stick and insert it into this computer when it is up and running



3. Download http://www.malwarebytes.com, run it and update it



4. Open the USB folder, drag and drop the setup.exe and program itself



5. Start you're infected PC up, click F8 (during the start-up), when the boot screen opens choose SafeMode with Networking (This may perhaps reduce the activity off the malicious files, but you will also have to scan the PC while it is up and running in Normal mode in order to erase this belief)



6. Drop it onto the Desktop and do a Scan

If that doesn't work



Boot to a rescue CD and run a malware scan. A great free one is Kaspersky

If you don't have an iso burner, you can use Burn4Free

If your computer doesn't boot to the CD, reboot and press F2, F12, Esc or Delete during bootup to get to the BIOS and set the CD as the first boot device.



Alternate 1. Remove the hard drive and place into an external hard drive enclosure, plug into a working computer that has up-to-date anti-malware and scan that infected drive.

Alternate 2. Back up your data to an external USB drive, then reinstall the operating system and applications.

Alternate 3. There are some well know anti-malware companies who have malware removal services.



PS:

Microsoft now has free anti-malware for home users called Security Essentials. Before installing it, remove all other anti-malware software.

To help prevent infection you can see if a site is safe before going to it by putting the URL in these checkers

Interesting video about virus and hacker threats. http://stophcommerce.com

Also, I can guess that you have some browser hiajckers installed that keep redirecting you to malicious websites, so you should also scan with Spyware Doctor anti-spyware for them.
