How do I remove the virus call trojan horse irc/backdoor.sdbot3.qlq?

I enjoy avg antivirus and window vista premium home OS


Answers: The FIRST article to do is DISABLE System Restore.
If enabled, this allows malware to secrete contained by the computer and re-install itself. To disable it, RIGHT-click on "My Computer." Select "Properties" afterwards below the 'System Restore' tab, check 'Turn stale system restore' IF not already checked.
The subsequent most nifty things that would comfort you are to use ONLINE scanners from websites to remove any malware on your PC. The current best online scanners I prefer are from Kaspersky antivirus and Bitdefender antivirus. Together, these 2 scanners will find ALL the discouraging stuff on your PC because they enjoy the BEST detection rate.
First, use Kaspersky's. (FYI: ALL these scan require you to agree to a EULA and install an activex control which is needed to execute the scan, so agree to them adjectives.)

*NOTE: Some scanners ONLY work next to IE or may not fully remove malware

Then scan near:

After using these, it's ESSENTIAL to install at lowest 3 antispywares. Do NOT use more than 1 antiVIRUS or firewall as they conflict.

Now if you can afford it, the best software to BUY are:

Kaspersky (BEST! =D )
Bitdefender (2nd BEst!)
F-secure (Same as Kaspersky)

If nearby's ever ONE profile you suspect is infected, you can try some single directory scanners which use MULTIPLE engines to scan ONE wallet.
They are @ virusscan.jotti.org or virustotal.com

If you're PC is squeaky verbs, re-enable system restore because it IS fitting to enjoy but we needed to shut it bad to demolish the malware.
Just RIGHT-click on "My Computer." Select "Properties" later beneath the 'System Restore' tab, UN-check "Turn sour system restore."


*Another piece to consider is using another browser besides Internet Explorer. It have profoundly of wellbeing holes,
making it smaller quantity undisruptive. I prefer Firefox from mozilla.org.
It's smooth to use, FAST, and have a great deal of elegant little add-ons you can toy around beside. It is also safer from exploits than IE.*


As other, things will alter. I only hope the best for everybody. I'm bound to return with some overprotective thumbs-down but at hand's individual one passageway to find things out---try it!
Keep an UPDATED Antivirus, Antispyware, & firewall and things will be fine. And other browse perceptively.
As a side record, please email me any/all websites you get the infection from or if any are popping up or hijack you so I can serve further shelter software's measures.
Sometimes you may attain a NEW and Unknown malware and I can submit it to be blacklisted/investigated to surety companies.
Hope I be competent to assistance. If I enjoy, please consider returning & departing a nice comment and
