All done! Thank u so much dfb, u've been very helpful Can i eventually contant u again in the future if some problem occurs or if i'll have some doubt regarding computer safeness?

ok now i have a little bit problem whit avast software updater: it says to me the update state is critical and says to download the latest version of java runtime environment 6; in the oracle website the version 7 was available so i downloaded it... but the software updater still notifies the critical state and says to download the latest 6 version... i tried to reset the database... could i uninstall JAVA 6 update 14 (64-bit) to solve the problem? thank u

hi dfb just one last question: are avast and malwarebytes sufficient to scan pendrive and external hard drive or are there any specific applications to have more reliable results? thank u, bye

I will install both of them free versions thank u for the help

thank u very much dfb! i will try all of these programs as soon as possible. I've already installed mozilla whit wot, adblock plus and webutation addons (i think i will install also comodo dragon) So do u think it could be safe to download avast free and use it to scan my external hard drives? I don't think they're onfected but i prefer to be sure. do u know any good program to do a checksum of the download? it happens every day to download software with "unknown" author, and learn to do checksum could be very useful i think. very complete and helpful!

hi dfb, thank u for reopening the thread, i'm right now doing all the procedure to update window (very boring and very slow... 4 year of updates!)... my pc now should be completley clean because how i said the recovery disks restored a new recovery partition (assuming the virus was here, but it's not sure)... can u give me some advice to scan my external hard drive and to keep my pc clean (now i have a norton trial version preinstalled, but it's not very good, fi the result was to take 2 virus in a week)? and some way to browse in a way as safe as possible (i discover comodo dragon, it seems to be very good)? are there any articles or websites where i can get any other good advices (such as bleeping computer for examples)? thanks, bye

Hi everybody About a month ago i made an accurate virus scans whit the help of one of the malwarebytes volunteer. Finally i decide however to reset my pc to factory condition using hp utility. I just reset my pc to factory conditions from about one month and i'd like to avoid to do it again. But now i have another problem Unfortunateley I was installing daemon tools lite and i clicked accidentally on a wrong download link.... I immediateley stop the installation... but however my browser get infected.... mozilla had strange po up and i re installed it(managing to fix it, now it's running correctly)... But explorer now is still full of strange pop up.... I run ccleanaer and deleted all app data and temp files.... i run norton antirus preinstalled in my factory conditiono pc and it find a tracking cooky; so i fixed it.... but interent explorer is still infected. What have i to do? could i re use all the program the person who helped me in the previews post sent to me? thank u very much!

thank u fred i already had read the article u linked and i think i will follow as soon as possible the instruction.... the alternative is to download a free version of windows from dreamspark (im a student) and to reinstall it to have a new clean OS without all the bloat ware hp utilities... i'm gonna decide as soon as possible... are there any good programs to make a system image i'd like to keep just in case something's going wrong?(a friend advice me on clonezilla)

hp.... my pc in particullar is an hp pavillion dv6 1330sl i know that there is a recovery manager

hi fred, i'm studing how to recover my pc or how to do the factory reset... i stored all my data on my removable disk and now i'm doing another fast back up on dvd.... the problem is that i haven't got the cd with the operating system.... i found that to do the factory reset i have to go in contro panel click the advanced recovery option and select the return to the factory condition button.... is this procedure possible even if i haven't got the cd whit the windows installer? have i to do an image of the system or a recovery cd or what else? Is there any procedure i can start from during the booting pressing f8? I'm not expert but i want to do averything by myself and i need to be sure my action won't damage the functionality of my notebook.... thank u very much

ok thank u d-fred, now my problem is that i have to save all my files on my external hard disk, but in this way i risk to pass the rootkit on it. Are there any scan procedure to control external memories (i would like to scan also my pendrives) after i use them to store all my data from the infected pc? I'd like to know if ther's any method to kill the rootkit, so i could store all my data on the external memories without fear to infect them. I run windows 7 on this pc but i haven't the system CD. I know that i could do the restore procedure to bring the pc at the factory beginning conditions. but i have not understand if there's any difference with the reformatting procedure, and if the effectiveness is the same. last question: AM I INFECTED? all the scan i made revealed no infection but the last one (that however detect a .exe and not a installed application or something else radicated in the system). So i don't know what to think about the real security state of my system. THANK U SO MUCH excuse the waterfall questions

ok eset found something in my download directory.... Effectively a few time ago a strange program was installed when i tried to update bit torrent... I instantly uninstalled it but the exe remain in my download directory.... the downloader of softonic i think it's not a problem... but i'm not sure. What have i to do whit theese 3 files now? My pc is running quite normally but i can't see the Windows/installer directory and i received spam to my university mail adress. I'm thinking to put all my files on an external hard disk and to format the pc and after to scan just the hard disk, what do u think about? thank 4 ur professional help i'm waiting 4 ur answers log.txt

EXCUSE ME...EVERYTHING'S OK I REEBOTED AGAIN AND EVERYTHING IS RUNNING LIKE BEFORE NOW.... HER'S THE LOG... THANK U SO MUCH!ComboFix.txt

i think something's gone wrong... I did what u saied but now when i try to open the combofix log or to open my browser or any other of my programs a window say to me that "a not allowed operation on a regitry system key signed for the elimination was attempted"(translate from italian).... in fact now i'm writing from another computer... What have i to do? I need to use my pc again as soon as possible.... I cannot do anything in this moment, even attach the log file of combofix... please help I try to say what i think could be the problem... before to do the operation i tryed to cancel combofix previous log because i thought it could give prolem whith the new one and a windows asked me to give the a dministration permission, so i closed the window and didn't eliminate the previous log, so everything should be ok....have i to format everything or what else?
