A few weeks ago, I started getting security alert pop-ups on my laptop from some "authentic looking" antivirus 2009 program, which I never installed.
Dell Inspiron 6400
Windows XP Pro SP3
McAfee Security Center 9.3
Peoplepc is my ISP (I live in a rural area and use dial up. I tried a Sprint Broadband card for a few days, but I didn't have a strong enough signal, so I'm still using dial up.
I ignored the popup and ran McAfee virus scan, which found several items (DNSchanger!K, Fakealertxxx and others) and which I removed. Every so often after that, the antivirus alert stuff would keep popping up and I'd rerun the virus scan and remove whatever McAfee found. I also started researching viruses and malware information on the internet and figured I was infected with some nasty stuff.
Last week, my laptop would not boot up completely. It would go through the bios load and the Windows XP screen with the blue scanner bar at the bottom. Afterwards, it would go to a black screen with just the white cursor arrow. I would power down and reboot. Sometimes it would get to the blue MS Welcome screen and stop. Other times, it would get to the desk top and stop. Sometimes it would go back to the black screen with the white cursor arrow. And sometimes it would boot up completely. Booting up completely, the icons would be "painted" slowly on the desktop.
I then tried booting in Safe mode. It always seems to boot up OK in Safe mode, but the graphics don't allow me to see my entire McAfee screen and I can't scroll around to see the rest of the McAfee screen, so I'm limited as to what I can do with McAfee while in Safe mode. I have run DDS, HiJackThis, SUPERAntispyware, Malwarebytes and GMER and I appear to have some major issues.
Right now, it appears my two biggest detected problems that I can't seem to get rid of are "\WINDOWS\system32\drivers\str.sys" and "\WINDOWS\system32\uacinit.dll". Also, several "UACxxxxx" files are also identified in red by one of the free software detection programs (don't remember which one).
There also seems to be something which keeps attempting to connect to the internet as my IE connection window keeps popping up every so often. I have IE set to use the Sprint Broadband connection by default, which I no longer have, so it never does connect successfully to the internet (dumb luck????).
So, I am seeking assistance in developing a plan of attack to resolve my laptop issue(s). ANY help would be appreciated. Thanks in advance.
