[Rastina Insannizhad]

Hi everyone
and
Hi, TwinHeadedEagle
Thank you, I followed your instructions and ran ComboFix as well, since I had the same problem with Win-7 (64 bit) and got the report (log) attached. Now I need further help if possible. can you or anybody else can help me in this regard please?

I don't know why you run ComboFix on your own???

WARNING!!! ComboFix is complex and very powerfull tool, that is able to destroy your system completely if run in wrong hands. It is not intended for everyday use. It should be run only when asked and under guidance by trained malware removal expert. Don't run ComboFix on your own!!!




Please download Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatibale with your system. If you are not sure which version applies to your system download both of them and try to run them.
Only one of them will run on your system, that will be the right version.

• Double-click to run it. When the tool opens click Yes to disclaimer.
• Press Scan button.
• It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
• The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

Thank you Mr. TwinHeadedEagle
Your help is highly appreciated.
Since I had problem with dllhost.exe COM Surrogate for its periodic (about every 10+ seconds) appearance and disappearance in the task manager and taskbar maybe with high CPU usage and its causing errors while I was typing and I was suffering from Slow operations, Photos view, delays in start-up and shut-down and the Task host Window in Win-7 (64 bit) platform, I searched for solutions on internet and found one of your discussions with instructions and recommendations about comboFix for similar cases. I tried to run it accordingly and call you for help having its log in hands which was uploaded above. anyway, I appreciate your reply and here is the logs for Farbar Recovery Scan Tool I ran lastly according to your instructions, please help with furthers process.
