My pc has been infected by those trojans:
Win32:Zlob-QT, Win32:Zlob-KB and Win32:Zlob-OO
The infected files are: laf27.tmp, laf28.tmp and laf29.tmp
I was able to move the infected files to the virus chest but I’d like to delete them. Can I delete those safely??
Most probably. But there is no hush to delete them. They’re safe into Chest.
Are you using Windows XP? Can you schedule a boot-time scanning?
Start avast! > Right click the skin > Schedule a boot-time scanning. Select for scanning archives. Boot.
It won’t be bad if you scan your computer with trojan removers too 
Hi Crazy :
Anything with "Zlob" should be investigated by an Experienced, volunteer Malware Expert usually
found on an antiSPYWARE Support Forum, so I recommend you go to the Forums of your
antiSPYWARE Provider; if you know of none, I recommend www.landzdown.com . Any such
Support Forum will want to see a "log" from the HijackThis program; therefore,
download HijackThis© from: www.thespykiller.co.uk/files/HJTsetup.exe .
At the download prompt, choose “Save”.
Navigate to the saved file and double-click the installer, HJTsetup.exe.
HijackThis will be installed on your computer at C:\Program Files\HijackThis, making an entry in the start menu and also providing a desktop shortcut.
When the installation is complete, exit HijackThis.
Ok i’ll try these. Thx for the help! ;D
