About a week ago, my laptop got a 'BackDoor Trojan Horse' virus. Then Windows directs me to download AVG Virus scan and i did that. Though having did that, i still have that the virus is stayed input in the laptop.

Before i downloaded the AVG, i have symatech antivirus in the com. But after AVG remove the virus that is found, the symatech still detect virus. Every time when i start the com, it pops up 2 to 3 symatech windows sayin that there is still virus.

I remove and remove a few times and yet, it pops up.
So, other than just scanning and removing, here are my qns:
1) is there any other ways to make sure that my com is virus-free?
2) Or has my laptop already been affected?
3) I download anime series from MiRc, is that why i get that virus?
4) Lastly, any safety measures to prevent from happening other than not dllin from MiRc if possible?

Really need help for this problem, for there are a lot of important documents in there.

Please and thanks.

What OS (Win XP/2000, etc) are you using? Did you try doing a scan in "SAFE MODE"? Have you performed any anti-spyware scans?

Are you using both AVG and NAV together on your computer? The concern with using more than one anti-virus program is due to conflicts that can arise when both are in real-time mode simultaneously. Anti-virus software componets insert themselves into the operating systems core and using more than one can cause instability, crash your computer, slow performance and waste system resources. When actively running in the background while connected to the Internet, they both may try to update their defintion databases are the same time. As the programs compete for resources required to download the necessary files this often can result in sluggish system performance or unresponsive behavior.

Each anti-virus will often interpret the activity of the other as a virus and there is a greater chance of them alerting you to "False Positives". If one finds a virus and then the other also finds the same virus, both programs will be competing over exclusive rights on dealing with that virus. Each anti-virus will attempt to seize the offending file and quarantine it. If one finds and quarantines the file before the other one does, then you encounter the problem of both wanting to scan each other's zipped or archived files and each reporting the other's quarantined contents. This can lead to a repetivite cycle of endless alerts that continually warn you that a virus has been found.

Symantec strongly recommends that you run only one antivirus program at a time. See here. I suggest you remove and use only one anti-virus.

What OS (Win XP/2000, etc) are you using? Did you try doing a scan in "SAFE MODE"? Have you performed any anti-spyware scans?

If your running Win XP/2000, download and scan with AVG Anti-Spyware 7.5 in "SAFE MODE".
(This is Ewdio 4.0 renamed. If you already have Ewido installed, please update to this version which has a special "clean driver" for removing persistent malware.) Be sure to print out the AVG Anti-Spyware Install-Scan Instructions and read the User Manual.

Then perform this online Virus scan: Trend Micro Housecall <- Use "Autoclean" and manually delete what it can't clean.
