I am facing two problems with my computer when I log in?

1) I get this message on my desktop.

Microsoft Visual C++ Runtime Library

Buffer overtime detected!

program: C:\Windows\Explorer.EXE ,

The moment i close it, desk top items disappear. I tried different antivirus software but the problem persists

2) I also get this web page HTTP 404 Not found error with IE 6, even when I switched to fire fox.

I use windows XP with SP2

Need understandable solutions, Thanks in advance.

I am facing two problems with my computer when I log in?free anti virus

Some of your system files on your system are corrupt or you could have a virus and or spyware on your system. First thing if would do is boot into safe mode and scan for virus. But if you don't have an up to date virus scanner, try the repair option. More info on this can be found here

Or if you have the manufacture restore cd try it

In the worst case situation you will have to reformat the drive and start from scratch.

If you don't have an anti virus I strongly recommend you get one.

I recommend getting Mcafee ($40)

I do not recommend getting Norton

An free alternative is AVG

Mcafee can be found at most dept stores. Best buy, Walmart, ect

To download AVG Go here

I recommend Ad aware to remove spyware. (Free)

And/or Spybot S%26D
