It seems my computer was infected by virus and I have no idea how to fix.My internet explorer wont work right and continue to get error messages when trying to open.Is there a way to fix for free?
Find sum free antivirus programs, like avast and update the virus database and perform a full scan, this will detect and remove the virus(s) found.
I would first try to fix it before reformatting it.

This is what I and it works for me.
You can print this and try it if you want.

*Download, install and the get the updates for the following, <<but DO NOT RUN A SCAN YET>>:

Adware


SuperAntispyware


*Then, DISCONNECT from the internet. UNPLUG it.

*Go to Start>Settings>Control Panel>Internet Options and delete all browsing history (cookies, temporary internet files etc). Check the box, Also delete files and settings storfree internet explorered by add-ons.

*Make sure your folder settings allow you to see the ALL your folders, Go to My Computer>Folder Options>View. CHeck all the show files boxes and UNCHECK all the Hide boxes. Click apply and ok.

*Go to C:\Documents and Settings\USERNAME\Local Settings \temp
Delete all files. (for each user)

*Delete all in recycle bin

*Next, boot up in safe mode (Tap the F8 key every few seconds as the system boots up until the screen Saying Safe Mode option appears).

*Now>> run the above spyware programs.

When through reboot normally.

I would also, download and install Firefox. Set the preferences to clear all cookies, temp files etc when you close it.
I have used AVG Anti Virus, Zone Alarm Firewall, Spy-bot Search and Destroy and Ad Aware both spyware killers for years. They are all free for personal use and I have hfree internet explorerad no trouble with Viruses Trojans etc. AVG does not slow the system down as much as some other products and Zone Alarm allows a lot of personal configuration unlike the Windows Firewall. They can all be downloaded from the following link On the home page select downloads and then the appropriate category.I also use Windows Defender from the Microsoft site. It is safe to use two anti-spy products but never use more than one A/V as it can cause conflicts. You should run A/V and anti spy weekly. Hope this helps
I agree with Bob. That's really the only effective way to do it free. If you want to surf the net then you need to be careful and use a proper antivirus.
reformatting your computer and reinstalling windows will get rid of it, and its as free as it gets. But you will lose everything on your computer.
