Helping with my Friend's Computer

[BRANDONN2008]

Hello. Now my friend's roommate was playing games online, and an IE window popped up saying a file was infected with some two-hundred something trojans. Anyone with common sense would see that is a scam to load viruses on the computer by clicking on it. My friend's roommate clicked on it though and now it won't go away. His computer eventually wouldn't let him click on anything. He somehow got to click on stuff, and I told him to install avast! and run a boot-time scan, which he did. It found a trojan and he said he deleted it. However, afterwords, the window still popped up, and he did another scan which revealed 3 more infections. Could you please maybe identify this threat and give a way to remove it entirely?

Hello BRANDONN2008,

Install malwarebytes antimalware from here: malwarebytes.org run a complete scan and post log here.
You can also do a scan with superantispyware.

This is a scam, scum/rogueware, fake security alerts, how would it know this unless a) it had installed an antivirus/spyware and b) run a scan. The answer is they can't know and it is just scare tactics to get you to part with money, visit a site, do a scan, etc. all of which are likely to get you properly infected. Not to mention if you part with money there is a likelihood you could be subject to capture of your credit card details and subsequent fraudulent use.

The only security alerts you should pay attention to are those of the security application installed by the user.

If you haven't already got this software (freeware), download, install, update and run it and report the findings (it should product a log file).
