Windows 7 - Virus! No system restore available

System restore error?

When i try to restore i get "System restore does not appear to be functioning correctly on this system. A volume shadow copy service component encontered an unexpected error. Check the application event log for more information (0x80042302). Im trying to do this because I obviously have a bad virus that is not letting me restore. It will also not let microsoft security essentials update, so i did it manually and ran a full scan, found nothing, spyware doctor, nothing, super anti spy ware, nothing, this virus wont even let me go into preferances, If i right click and go to personalize it gives me an error box that says explorer.exe class not registered. I am using windows 7 and really need help. please if you need more information ask me, plus my premade rig from Best Buy didnt come with a windows 7 disk (P.s my audio stopped working also and my internet connection icon in my tray shows that its not connected and say connection not available, but im posting right now on the forums, hope that gives some insite) (P.s.s I have tried sfc /scannow
to no avail get error windows restore protection could not start repair service, and I ran as admin

got this from yahoo answers, I dont know what he means by rebuild, I dont have my windows 7 disk so i dunno my options,

Hello kaoticsolja and welcome to the Forum

I'd try to download the Malwarebytes free edition. (Make sure you update the signatures before running it.) Then reboot your machine so you can start it in Safe Mode. Run the full Malwarebytes scan and see if it detects anything.

Safe Mode

Let us know if you had any malware detected and/or if you're able to get into system restore. NOTE: if you did have malware it's possible that your system restore was corrupted too. I wouldn't rely on using any restore points and it might be a good idea to delete all of them and create a fresh restore point. Use Method 2 in the tutorial. Once you've deleted all but the most recent restore point, create a new one and then you can go back to delete that one remaining earlier restore point.

System Protection Restore Points - Delete

I did so and found nothing, I had already tried that but thought what have i got to lose, and no restore still dosnt work. I used maleware and teh previously stated anti virus. I have came to a new problem, I cannot update windows, If i click windows update it says the service is not running and i must restart, obviously this isnt working for me,

I read this on another forum
Right-click on My Computer and select Properties: What Windows version is displayed on the resulting General tab (e.g., Windows 7 Release Candidate 1)?

Start > Right-click on Run and select Run as Administrator > (type) winver > OK : Write down the complete, second line of text displayed in the resulting window & post this information in your next reply.

The above notwithstanding, your best course of action would be to format the hard-drive & do a clean install of Windows if you've not been able to install updates since 05 .


I tried all this and nothing, I also read maybe an extreme view, they said immediatly take my computer back to the retailer and demand a refund as my computer is critically in trouble. PLEASE HELP lol sorry to yell

Welcome to Seven Forums. I have contacted a member who is really proficient with Security and virus problems. She is offline right now but hopefully she can help you out.

If it was my system I would just do a clean install, I know it's a real pain but sometimes it's the only way to really know you've gotten rid of anything harmful to your system.

Not a problem with the yelling . I know how frustraing computer problems can be. In order to help you better, could you fill out your system specs. At the top of every forum page Quick Links > Edit Your Details > Edit System Spec. It would also help to know when and where you bought your machine in case we need warranty info.

Depending on the manufacturer, you might already have a link in your start menu or perhaps a hidden partition on the hard drive to return your machine to factory settings (the exact condition it was in when you brought it home and took it out of the box.) I think this would be a better option because a clean install will wipe everything off the hard drive. In either case, you'll have to back up any important files, folders, photos, etc but we can help with that too.

I agree! I would do a 'clean' install too.

Ok so I added my specs, Im not sure how to do a clean install because I have no windows 7 disc so how do I go about recieveing one or downloading it. I purchased it at best buy. In the box came a Desktop PC warrenty card Its a 12 month, which is still valid.
