When ran, the worm copies itself to Windows directory with the name FUNNY.SCR and sets itself as the screen saver, by writing the following registry keys:

HKEY_CURRENT_USER\Control Panel\Desktop\"SCRNSAVE.EXE" = "%WINDIR%\FUNNY.SCR"
HKEY_CURRENT_USER\Control Panel\Desktop\"ScreenSaveTimeOut" = "300"

so that it will always run as screen saver after a 5 minute timeout.

Also it copies itslef to Startup folder so as to run with each Windows session:

%DocumentsAndSettings%\%User%\Start Menu\Programs\Startup\STARTWIN.EXE

Then it scans the hard-disk drives and deletes multimedia files containing one of the following strings:

Liviu Guta, Liviu_Guta, Nicolae Guta, Nicolae_Guta, Copilul de aur, Copilul_de_aur, adi de la valcea, adi_de_la_valcea, adi de vito, ady de vito, florin salam, florin_salam, adrian & camy, stana isbasa, adrian cm, adrian copilul minune, adrian_copilul_minune, alina si costi, copilul de aur, dani de la deva, gabi din buzau, gabi de la giulesti, liviu pustiu, guta jr, guta & sorina, printesa ionela, don genove, jean de la craiova, cristian gusatu, ovidiu mititelu, sorinel pustiu, lucian seres, mihaela minune, minodora, n. guta, n.guta, nico cu carbon, nico_cu_carbon, sile dorel, vali vijelie, carmen serban, petrica cercel, nicu paleru, cata boss, liviu_guta, stefan de la barbulesti, florin peste, liviu cu mirela, sorina & florinel, puiu codreanu, catalin de la buzau, daniel dinescu, relu pustiu, victor spaniolu, vali raicu, adi caval, carmen dobre, sorinel copilu de aur, as da zile de la mine, sunt seful vostru pana mor, chefdechef, chef de chef, dusmanii mei, plange sufletul, jumatate tu, jumatate eu, ce le-nnebuneste pe femei, sa cante manelele.

The worm sends mails with itself to all entries in address book of Outlook, and also scans Yahoo Messenger log files to gather new mail addresses.

Also it creates a [logfile] called M.TXT in the root of C: where it logs its actions. The log file may be erased.
