What to do ??? Trojan infection.

Problem File:
C:\Program Files (x86)\MyWebSearch\bar\1.bin\MWSSRCAS.DLL

Type:
Win32/Virus.WebToolbar.c34

So I did a scan on my system today with 360 Total Security Malware System Protection and it turned up a critical file. I know nothing about virus/malware programs and all I did was quarantine the file in question till i could get some feedback on how to handle it. Program stated that it was a Trojan and that the file description was MyWebSearch_Search Assistance "whatever that means" with a valid digital sig. Now what do i do after I quarantine it. Do I remove the ext. or do I remove the whole program file stran & then reinstall.

Would appreciate any advice from some of you experienced tech. savie people out there to help me solve this problem in which I am facing and maybe some 101 on virus program do's and don'ts.

Hi and welcome to SevenForums,
Post these scan results,

Review Jacee’s instructions to run Adwcleaner here post #7,
Ignore the title of the thread,
Instant Savings App
On the BleepingComputer site use the button that looks like this,

You can use these free tools to see if they find anything,
Manually Update them before running full scans,
Try not to use your computer while the scans are running, (one at a time of course).

See this tutorial on how to download and run Malwarebytes,
Malwarebytes Anti-Malware Free
Also use the Custom scan option not the Threat scan,
Malwarebytes | Free Anti-Malware Detection & Removal Software
SAS is safe to remove anything it finds
SUPERAntiSpyware | Remove Malware | Remove Spyware - AntiMalware, AntiSpyware, AntiAdware!

I personally would be very cautions of a security program from China.

ThrashZone suggestions would be a good place to start.

I notice in THK3 System Specs.

Antivirus Microsoft Security Essential / 360 Total Security

This shows two security anti virus programs.
You do not want more than one Anti Virus Program on one computer at one time.

I personally would keep MSE.
