Good afternoon, everybody.
My pc is shared by other 3 members of my family, nobody is under age and they have the basics for using pc. Yesterday, I was told one of them downloaded something and the pc got many unwanted programs and files, meaning weird softwares were installed and highly probably viruses were gotten here. I tried restoring the windows but without success. Then I decided to get RevoUninstallerPro to get rid of those unwanted programs, by deleting not only the programs, but also the keys, registers and so on. Whenever I went back to RevoUninstallerPro, I saw some of those programs names but no action could be taken. Then I decided to get Adwcleaner to get rid of leftovers and I had to run it about 7 or 8 times. Meanwhile, I also used Kaspersky Virus Removal Tool about 5 times, doing a full scan once. In the last two attempts of using Kaspersky Tool, it found no threat, same with adwcleaner; now they found nothing, but two things intrigue me: a weird message appears whenever I restart the windows (I'll tell about it later on) and Windows Defender was disabled and gives me error 0x800704ec. I searched on the internet how to enable Windows Defender, through cmd and also going to regedit to give it total access and control over all users, but none of those let me enable it again. I ran Windows Defender about 3 weeks ago and by then I didn't have the windows warning flag to warn me about that problem (I have that flag now telling me to enable Windows Defender as soon as possible).
The other problem is that, whenever I start windows, a window without any program name appears and shows random stuffs, ranging from ''hot deals'' to buy things to installing weird softwares and toolbars (MyStartSearch, for instance). Sometimes it popos out of nothing saying ''Thank you for using our software, would you like to install this and that?''. I tried to start windows without internet conneciton, but the window appears without anything to say (due to lack of internet connection), but it still appears anyway. The last time I started windows, I got to be calm and try to extract the max of information I could from that window and I got this:
I was really hoping it could be connected to Internet Explorer browser, since it was the only browser I haven't reinstalled (I reinstalled Google Chrome only). Also, during the unwanted programs infection, Opera browser was installed, but then I removed it - hopefully - completely.
So, to sum up: My pc got infected by unwanted programs that disabled Windows Defender and made a weird window appears whenever I start windows, showing me offers and random softwares for installation, even though I removed them all with RevoUninstallerPRO.
Maybe the following infos will help us to solve this:
- Unwanted programs installed: CinemaPlus, Shoppers, YTDownloader, SavePass, adblocker, Opera browser and SearchProtect (it's kinda an anti-virus, so I believe it caused Windows Defender total disable).
Pc config:
- Processor: intel i5 4440
- Mobo: GA-B85M-HD3
- GPU: GTS 450 Zotac 1GB DDR 3
- PSU: Thermaltake 550W
- RAM: 4GB
- Windows 7 Ultimate 64 bits
P.S.: I'm thinking of formatting the system to start anew, but then I have tons of important files here. I was considering to use flashdrives to store my files and then put them in the newly installed windows. Thing is that I'm afraid that flashdrive that will get the important files might end up corrupted by some weird virus and corrupt the new windows. Would it hurt the flashdrive, even though Kaspersky says there's no threat?
Thank you very much in advance.
