Dear Matt and Exterminate it,

Thank you so much. This seems to have fixed the problem. Wow. That virus was in there pretty deep. A*G didn't even identify it. S****t would just freeze up when I tried to run it. But the update from Exterminate It, removed it.

Again, thanks.

Kind Regards,

A trojan is a program that is disguised as legitimate software but is designed to carry out some harmful actions on the infected computer.

Unlike viruses and worms, trojans don’t replicate but they can be just as destructive.

These days trojans are very common. Trojans are divided into a number different categories based on their function or type of damage.

Be Aware of the Following Trojan Threats:

Rauser, Bloiscom, HDOpt, Barbarie, Pigeon.AWJK.


Browser Helper Object, or BHO, is a dynamic link library (DLL) that runs whenever Internet Explorer is started. Generally, BHOs are included in installation of third-party programs where they are offered as enhancements of the browser functionality. For example, many Internet Explorer plug-ins are in essence BHOs.

BHOs can be installed silently or “legitimately” when a user fails to read the fine print included in the freeware program’s EULA (End User License Agreement).

Because BHOs are small programs, they can do anything that other programs can do. It’s not easy to detect the BHOs installed on the computer. This enables hackers and other malevolent users to employ the BHO functionality in their interests, for example, secretly install adware programs or gather various statistics on the user’s browsing trends.

Be Aware of the Following BHO Threats:

Whazit, NCast, Search Enhancer, Cytron, KBDPQL1.

How Did My PC Get Infected with ClientMan.MSMC?^

The following are the most likely reasons why your computer got infected with ClientMan.MSMC:

Downloading and Installing Freeware or Shareware

Small-charge or free software applications may come bundled with spyware, adware, or programs like ClientMan.MSMC. Sometimes adware is attached to free software to enable the developers to cover the overhead involved in created the software. Spyware frequently piggybacks on free software into your computer to damage it and steal valuable private information.

Using Peer-to-Peer Software

The use of peer-to-peer (P2P) programs or other applications using a shared network exposes your system to the risk of unwittingly downloading infected files, including malicious programs like ClientMan.MSMC.
