Hi. Am very new to this...so please forgive any mistakes I will make.
I have been having problems with my pc ever since I installed xp sp2. Recently I tried to access www.avast.com to download an antivirus program someone told me was good because I had removed spybot search & destroy, lavasoft adware, att/yahoo antivirus and just wanted one good program.
Problem was as soon as i typed in address in browser and hit go...browser immediately closes. I tried several times. Also, whenever I type the word "virus" into a search engine, my browser closes. I am currently on my kids pc to try & figure out what to do next.
It looks like I need to download hijack this first...but am afraid I won't be able to do on the problem computer. If I don't hear back right away...I will try to get that done at least. I have many more issues with said computer, but this is where I need to start.
It's Saturday, and I'm going out; this is rushed, but should help [playing a bit blind, here...], do these things in this order: ==Download this temp file cleaner from http://www.atribune.org/ccount/click.php?id=1 --click in the download window to run it, and when ATF Cleaner opens go Select all, and then Empty Selected. Next click Firefox [if you have that browser..] at the top, Select All again, and Empty Selected again. Follow that procedure also if you have Opera. Close ATF. ==download HostsXpert from http://www.funkytoad.com/content/view/13/31/ -click the top button Make Writable if it is available -click Restore MS Hosts File button. ==Please use IE to do an online scan at panda:- http://www.pandasoftware.com/products/activescan? -select a link to the scan... free online virus scan...., enter a valid? email and follow through, choosing My Computer for a full system scan. Post the log it produces here. ==GET AVG antispyware 7.5 here.. http://free.grisoft.com/doc/5390/lng/us/tpl/v5 or here.. http://free.grisoft.com/freeweb.php/doc/5390/lng/us/tpl/v5#avg-anti-spyware-free -Install it and UPDATE it. Start AVG a-s 7.5; -under Scanner/ Settings please change the default action from Recommended Actions to QUARANTINE, and run the complete system scan. -press Apply all Actions and Save the log file. Post the log file. ==download hijackthis: http://www.majorgeeks.com/download5554.html -copy it to a new FOLDER placed either alongside your program files or on your desktop and then... rename hijackthis .exe to imabunny.exe -in that folder start HijackThis by dclicking the .exe; now close ALL other applications and any open windows including the explorer window containing HijackThis. -click the Scan and Save a Logfile button. Post the log here. Should keep you quiet for a while.
Just a note... It is the hosts file which is blocking your browser from some sites. If you wish to clear your hosts file manually [C:\Windows\system32\drivers\etc\hosts] you may not be able to save the changed/corrected file. This is because some security applications, possibly also various malware, will lock your Hosts file ... Go Start, run, type cmd -press Enter. Paste this line into the window at the prompt, press Enter, close the window and try to save the file again. attrib -r -h -s %SystemRoot%\system32\drivers\etc\HOSTS ..but Hoster will do all this for you if you wish.
