Malwarebytes vanished-trojan horse

[suezeq]

When i turned on my computer this morning, AVG found a trojan horse & its scan said it came from Poker Stars; the scan said Quck Time & MalwareBytes were infected. MalwareBytes would not open up at all. I let AVG quarantine the virus, then remove it. I uninstalled Poker Stars, Quick Time & MalwareBytes. AVG scan now says my computer is clean.

1) I purchased MalwareBytes 9/29/10 - can I now reinstall it with my disc which was mailed to me?

2) can i reinstall Quick Time from online now?

This was a false positive on the part of AVG and these files were not infected. You can reinstall the latest version from here and reuse your serial key.
