After a lot of personal research, straightforward testing, and lessons learned, I came up with the following freeware solutions for keeping my system up and running.

FIREWALL
– COMODO Firewall Pro

ANTIVIRUS
– AOL Active Virus Shield (based on Kapersky)
– a-squared free

ANTISPYWARE
– SUPERAntiSpyware Free Edition
– Microsoft Windows Defender
– SpywareBlaster
– McAfee SiteAdvisor

REGISTRY CLEANER
– Advanced WindowsCare V2 Personal
– CCleaner

ANTISPAM
– SpamBayes

DEFRAGMENTER
– Speedfrag (a bit akward to use at first, but simply the best one available for free)

MEMORY OPTIMIZER
– Cacheman

All those software are free to everyone for personal use, they are also easy-to-use, non-intrusive (almost no pop-ups windows) and low-memory consuming.

My laptop is now booting up in 55s with 659 Mb of free RAM available (out of 1Gb total), and is decently fast.

I consider it good, but I would like to make it even better.. Any advise?

I believe my friend has a virus on her computer. She was downloading from lime wire and the screen went blank. Wont boot into safe mode and she does not know if she has any virus protection. Assuming she does and it’s just not up to date here—if I pull the hard drive and put it into a hard drive enclosure and hook it up to my laptop to scan it if she has virus protection will it clash with my virus protection and lock up my laptop.

I need virus protection for my laptop and Im a little tight on cash so I prefer a free one.

I recently had to leave my laptop in the hands of some techs to do a diagnostics check on my computer. It turned out I needed a new hard drive, which sucked. But when I left it with them, it had the software disk to my tablet in it, and it came back without it. I’m assuming they needed to remove it to reinstall Windows, but forgot to return it to me.

If I can’t manage to get the disk back from them, does anyone know where I can download this software so I can get my tablet reinstalled?

Thanks in advance.

On my Acer Aspire 4250 laptop my screen went black and a "Windows Error Recovery" message appears, it says "windows failed to start. A recent hardware or software change might be the cause" and when I tried the Startup Repair it wouldn’t work and I couldn’t reformat it either. How do I fix it without a disk?
