After I logon to my Windows 7 machine, the computer seems to freeze. Every once in ahwile I'll be able to do a little but it is painfully slow(3-5 mintues for one action). Everything runs normally in safe mode.

Originally I thought my virus software of kaspersky 2012 was causing problems at startup, so unwisely I removed it. I can't get the machine to run long enough to get it reinstalled.

The computer will start and run in safe mode. I have downloaded combofix. It runs and creates the log. It runs at an acceptable speed in normal mode after the combofix reboot where it is creating the log. However I can't launch any program because it says that a registry is marked for deletion. When I restart it goes back the computer being unusable.

Sometimes I can get task manager up and sometimes is gives an error that that it is unable to launch. I can't even launch my computer or google chrome.

Any help would be appreciated. I am fairly comfortable working on computer as I have .NET programming background.

I have also disabled all the startup items in msconfig.

Do you have another computer you can plug the laptop HD in as a slave to scan it?

You can try booting into safe mode with networking and getting a free antivirus installed, try avast! and do a boot time scan if you think it is a virus. You can also try Superantispyware or Malwarebytes to check for malware. I am not very proficient with Combofix sorry.

Good luck.

Because you have combofix log files that may shed light on your infection, it would be best to post in the Virus, Trojan, Spyware, and Malware Removal Logs Forum. They will get you straightened out.

Just follow the instructions in the "Preparation guide for use..." link.

Brooks

Thanks for the replies. I found the issue finally this morning by going through the event logs. There were two dll's that were compromised in the System32 folder. I replaced them from another machine and the computer is running great. Again thanks for the help.
