Windows 7: Multiple Windows 7 errors, possibly caused by a virus.

Multiple Windows 7 errors, possibly caused by a virus.

So, let me start with an introduction how it happened. I've been using my computer the same way I do every day. Browsing internet as my friend called me on skype. I tried to accept, however, I wasn't able to. Even if I clicked the accept button, nothing would happen. Thinking it's just some regular error, I force shut-down process of skype and tried to reopen it. Here I received a strange looking error. Do not remember it exactly. Went something like - "exception EoLeSysError in module Skype.exe..." Also, I should mention I have a mouse with editable buttons, so for this I use X7 Oscar Editor. It was working fine, however when I tried to start it up that day Windows Installer popped up and would try to "reinstall?" it. I'm not actually sure what was that about. What I know for sure is that that was the first unusual thing that happened. Not concerning myself with this, I restarted my PC, getting met with an error regarding X7 Oscar Editor: "Unregistered class." After that I tried to start up Skype. This time, no error message popped up. It seemed to start up alright, but it wouldn't respond if I tried to call/chat, basically anything. If I should guess, I'd say that nothing that was running during the time I decided to restart the PC wouldn't work properly. Tried to start League of Legends, since I remembered I had that running and was met with a "Not responding" message. Trying to run an in-built launcher repair wouldn't work. At this point the first thing that came to my mind was to run some sort of registry cleaner. So I did so. CCleaner did the job for me. I run a clean-up. Didn't do anything for me except only bring more corrupted files and problems. At this point I'd try to look through the control panel, but yet again, I was met with an unexpected occasion. In the control panel I couldn't click the blue link, like "Uninstall program" and so on. However I could still click every other link, and somehow get where I wanted to be. I tried to uninstall Skype, Avast and X7 Oscar Editor along with some other stuff (that wasn't working) I thought could possibly be causing the problem. Wasn't able to though. Different kind of messages popped up. This could be related to a corrupted Windows Installer (not sure, confirmation?) I tried to run Windows in safe mode with networking to see if I'd figure something out. When I switched back to normal boot my theme would change to a default one, so I went to change it, however, another error message. "Explorer.exe Server execution failed" Also, Windows doesn't recognize Avast, even though it's still installed and working properly. Not being sure about it working properly I figured I might as well try it out and see if there are any viruses on my PC. Did a complete system test and found a handful amount of viruses I was sure weren't there a week ago. The one that caught my attention the most was "Dropper GEN Trojan" Even after getting rid of this, nothing changed. So now I'm here, as the last resort before I just try to reinstall my windows completely. Btw, I didn't make any system recovery points, which was pretty dumb of me, since I thought they wouldn't be necessary. Silly me.

System Restore is a most vital front line defense for problems like this, so always apportion as much space as possible for Restore Points and makes sure they stay turned on. You may end up needing to reinstall because you didn't assure this, and turning it off is sheer foolishness: System Protection - Change Disk Space Usage

Work through the Troubleshooting Steps for Windows 7.

If you lose functionality for any steps, there are parallel steps from boot to be run from Troubleshooting Windows 7 Failure to Start.

Report back results as you go as there may be other steps indicated.

Alright, I can't even get through the first step. I need to install Malwarebytes, but for that, my Windows Installer would have to be working properly. However, as I mentioned earlier, it isn't. Right now I am trying fix this issue first. Nothing worked so far. I'll you updated if I somehow fix it.

Run SFC /SCANNOW Run in Command Prompt at Boot from the booted Win7 installation media or System Repair Disk.

If it finds files to repair then run it again until it finds no more.

Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.log... on the second run. First run did find corrupt files and fixed them.
Attaching the results of the check.

Have you run the bootable AV scans suggested as first step in Troubleshooting Windows 7 Failure to Start ?

If not do that now. I would run at least two. Once clean you can also rescue your files using one of the
FREE Bootable AntiVirus Rescue CDs Download List .

Then run SFC from boot disk again up to 3 times to see if files will repair.

If not consider a Repair Install .

However if this is an original factory preinstall or does not measure up to the perfect install compiled in
Clean Reinstall - Factory OEM Windows 7 then I would rescue my file and invest now in the best possible install, which you will get and keep if you stick with the steps in the tutorial.

So you're suggesting I should just reinstall the windows right now? Well, that's what I was actually planning to do anyway. Well, thanks for your time. I appreciate it.

Back up your files to quarantine and only reimport them later after a full Malwarebytes and AV scan is done on them.

Then be sure during the booted Clean Install Windows 7 that you delete all partitions during Steps 7/8 to wipe out any infection on the disk.
