System Windows XP Service Pack 2
Avast Professional V 4.7
A few weeks ago I ran a full system scan and Avast! found Trojan GpCoder in a few files--all were .msp files (1 in "downloads" folder--a Service Pack for ArcGIS and 1 in Windows/Installer folder.)
Avast! was unable to rename & move, move, or delete files.
I deleted the ArcGIS service pack (I can just re-download that one) but didn't want to mess with Windows file yet.
Ran a boot scan using Avast!. No viruses detected.
Downloaded AVG and trial version of McAfee--no viruses detected.
Avast! is still finding Trojan--now in more than 1 file in the Windows\Installer. All of the files are .msp Windows Installer Patches, all are 62,857 kb or 70,097 kb. If I right-click on the .msp file and choose "Scan", no virus is found.
Uploaded one of files to
http://virusscan.jotti.org/ at advice of Avast! technical support. One file had a Trojan (not the same one) found in VBA32 (paranoid heuristics), but not in any other (including AVAST!) the other had a Trojan found in AntiVir and ArcaVir--again different from original, but not in any other.
I am at a loss. Avast! can't process the file, but I am not convinced that this is a false positive.
Ran Hijack this and visited
http://www.hijackthis.de/index.php?langselect=englishNothing unusual found there.
Also running Spyware Doctor--no problems found there.
I have been having trouble with some applications crashing or hanging--but they are famous for doing that under the best of circumstances.
Any help would be VERY MUCH appreciated.
