Infected, no network connection, cannot run Malwarebytes

[mdonovan]

Hello, I am having issues with my home computer. I have Windows XP SP3 and Avast Internet Security. I did not have Malwarebytes on my computer, so I tried to download it onto a memory stick at work and then run it at home off the stick. I get an error message Run Time 13 mismatch when I try to scan the files. I cannot install the Malwarebytes since I have no network connection. My Avast real time web shield is turned off and I now my computer shuts off occasionally by itself. Every time I run a scan and a boot time scan with Avast (I have done about 12 scans) , it finds infections and deletes them, but nothing allows me to turn the web shield on and I still cannot connect to the internet with Firefox or IE.

Is the Malwarebytes not running because I downloaded it onto a memory stick or is it an issue with the software?
