Hi pol2221,
Download
Ad-aware SE and update it (the Globe icon, then Connect). Then click on "Perform Full System Scan". Uncheck "Search for negligible risk entries" and click on "Next". Eliminate all that Ad-aware finds.
Restart your computer after cleaning with Ad-aware and scan again. Repeat the process until no further items are found as bad.
Download
SpyBot S+D.
After installing the program, click on "Search for Updates" and download what the program finds.
Click on 'Search & Destroy' and on "Check for problems". Delete what it finds.
Check your computer with the following free anti-virus/anti-trojan products.
Housecall Anti Virus Panda Anti Virus Trojan Scan Bit DefenderAnd, here's the link to
McAfee AVERT Stinger and instructions for use.
Be sure and put a check in the box by "Auto Clean" before you do the scan. If it finds anything that it cannot clean have it delete it or make a note of the file location, so you can delete it yourself.
Please enable everything you have turned off in 'System Configuration Utility' (MSConfig.exe). This way your system will not hide any potential malware and hijackers. What I cannot see, I cannot fix!
Download HijackThis.
http://www.bleepingcomputer.com/files/hijackthis.phphttp://209.133.47.12/~merijn/files/HijackThis.exehttp://www.downloads.subratam.org/hijackthis.zipIf you are on Windows XP,
extract the file. Do not just doubleclick on it! This opens HijackThis in a temporary folder. This would interfere with the possibility to make back-ups.
Unzip to a folder other than your Desktop or the Temp folder. Then, doubleclick HijackThis.exe, and click "Scan".
When the scan is finished, the "Scan" button will change into a "Save Log" button.
Press that and copy and paste its contents in this thread.
Most of what it lists will be harmless or even essential, don't fix anything yet. Someone will be along to tell you what steps to take after you post the contents of the scan results.
