Cheers! I have two major issues that I can't handle myself: 1) (the smaller one) After starting my computer there's this one pop-up error that occurs 'smgr32.exe error- can't find the component- there is a zlib4.dll file missing. Reinstalling the aplication might solve the problem'. It doesn't affect the systems work that much if at all, but it is a nuisance and just looking at it makes me feel sorry for my PC. 2) (the big one) After browsing youtube and a site with mature content and after closing a few adds this popped up: 'HTML/Infected.WebPage.Gen [virus]' in my Avira scan and i got so scared i pressed enter... and the default process was deletion. My Firefox crashed and now I can't log onto any web service (I'm writing this message from my other PC with a Mobile/Dial-up internet connection) nor any of my internet games. Tried rebooting the system, scanned it with Avira again, returning it to it's previous state, uninstalling any programs that I've installed over the past 24h, but still nothing works... I'm completely out of ideas. My modem works, all the lights are on and my cabel tv and stationary phone seem to be unaffected, but I can't log on to ANYTHING. Internet exploarer just gives me a blank page asking me if I'm sure I've written the addres correctly, same for Firefox. I'm just a poor philology student making a living out of tutoring, I don't know zippo about computers. Please, help. I'm providing the full message that popped up after the accidental deletion: 'Virus or unwanted program 'HTML/Infected.WebPage.Gen [virus]' detected in file 'C:\Documents and Settings\Owner\Local Settings\Application Data\Firefox\Profiles\omi8g82x default\Cache\_CACHE_001_. Action performed: Delete file. I would really appreciate a fast response since I have a lot of friends that I can't communicate to from this computer via Skype and would love to have a reasonable download/upload speed again. The second issue is top priority. Thank you in advance.
