SOLUTION
Step 1
Before doing any scans, Windows XP, Windows Vista, and Windows 7 users must disable System Restore to allow full scanning of their computers.
Step 2
Note that not all files, folders, and registry keys and entries are installed on your computer during this malware's/spyware's/grayware's execution. This may be due to incomplete installation or other operating system conditions. If you do not find the same files/folders/registry information, please proceed to the next step.
Step 3
Remove the malware/grayware file that dropped/downloaded TSPY_DYRE.YUYCC. (Note: Please skip this step if the threat(s) listed below have already been removed.)
Step 4
Search and delete this file
- %AppDataLocal%\{Random Characters}.tmp
- {Malware Path}\{Random Characters}.tmp
- %AppDataLocal%\Cab{Random characters}.tmp
- %AppDataLocal%\Tar{Random characters}.tmp
- %User Temp%\Cab{Random characters}.tmp
- %User Temp%\Tar{Random characters}.tmp
- %AppDataLocalLow%\{random characters 1}.bat
- %AppDataLocalLow%\{random characters 1}.sdb
Step 5
Delete this registry value
Important: Editing the Windows Registry incorrectly can lead to irreversible system malfunction. Please do this step only if you know how or you can ask assistance from your system administrator. Else, check this Microsoft article first before modifying your computer's registry.
- In HKEY_LOCAL_MACHINE\System\CurrentControlSet\services\SharedAccess\Parameters\FirewallPolicy\FirewallRules
- (guid) = "v2.10|Action=Allow|Active=TRUE|Dir=In|Protocol=6|App=%Windows%\Explorer.EXE|Name=Core Networking - Multicast Listener DOne [ICMPv4-In]|"
- (guid) = "v2.10|Action=Allow|Active=TRUE|Dir=In|Protocol=6|App=%Windows%\Explorer.EXE|Name=Core Networking - Multicast Listener DOne [ICMPv4-In]|"
Step 6
Scan your computer with your Trend Micro product to delete files detected as TSPY_DYRE.YUYCC. If the detected files have already been cleaned, deleted, or quarantined by your Trend Micro product, no further step is required. You may opt to simply delete the quarantined files. Please check this Knowledge Base page for more information.
