Hello, After couple of days of stress with my pc problem i found this site and i folowed all the steps as they listed in thread about viruses removal steps instruction (all 15 of them) History of the problem: My computer got infected by virus serial99.com and it did nasty things to it. I couldnt bring Task manager, couldnt find 'Run' and 'Shut down' button when i click Start. My browser got overtaken by this evil thing. Thanks to you guys and this forum i managed to fix few problems that serial99.com caused to my computer. I followed every step in order. And attached the final HJT scan log. Please , be so kind and check if everything is ok. Additional info from scan: Panda Anti-Rootkit result: No rootkits have been found. I still experience few problems with opening web pages (very slow) and one of them is when something went wrong with registry keys me and my husband desided to run windows set up from windows XP cd ( don't ask me why..T_T) and it stuck somewhere . When i start my PC it brings me to Troubleshot screen where i have to choose what to run : Windows XP Home Edition (which our current) or Windows XP setup. Please,help me get rid of it, how do i do this? Thank you in advance.
