You said you updated Norton Anti-virus
, you found a trojan using Kaspersky anti-virus
and then go on to say that you use AVG
? Are you using three
The concern with using more than one anti-virus program is due to conflicts that can arise from them both running together at the same time in real-time protection mode. 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.
While operating in real-time mode, each program will often interpret the activity of the other as a virus and there is a greater chance of them alerting you to "False Positives". Further, if one Av finds a virus and then the other also finds the same virus, then both programs will be competing over exclusive rights on dealing with that virus. Each piece of AV software will attempt to seize the offending file and quarantine it. If one AV finds and quarantines the file before the other one does, then you encounter the problem of both AV's 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.
...didn't want to download any more to it untill this is resolved, can i download hjt and run it then send the log .
You may have to download other tools to get your problem resolved and of course you can download Hijackthis and post a log. But first I suggest you start by removing all but one anti-virus program.
If your running Win XP/2000, download and scan with Ewido Anti-Spyware v4.0
in "SAFE MODE
Print out the Ewido Install and Scan Instructions
If this does not solve your problem, then download and run Hijackthis follwing the directions in the Prep Guide which you read. Post a log
